"I was earning about ₹ 5000 per month and found the work monotonous. That was when I thought, I should do something more", he recalled in an interview. Karthi got a scholarship for his higher studies in the United States, and enrolled at Binghamton University, New York, where he earned his Master of Science in Industrial Engineering. While pursuing his master's degree, he also took elective courses on filmmaking.During his stay in New York, Karthi worked as a part-time graphic designer. He then decided to pursue a career in filmmaking; he attended two courses in basic filmmaking at State University of New York. He stated: "I always knew I wanted to be in films, but I did not know exactly what I wanted to do. I loved movies and watched a lot of them. But my father insisted that I get a good education before I joined the film industry".
2004-2007: Debut success
When Karthi returned to Chennai, he met director Mani Ratnam and got a chance to work as an assistant director for the film Ayitha Ezhuthu because he wanted to become a film director and preferred directing to acting, though he did appear as an extra in Aaytha Ezhuthu. He continued to receive acting offers and his father convinced him to take up acting, telling him " ... one can always direct films, but one will not get a chance to act once you grow older". He accepted his first acting assignment with Priyamani as female lead in April 2005. When director Ameer approached him to play the titular character in the film Paruthiveeran, he accepted the offer because the film was " ... so compelling". The filming started in July 2005 and experienced financial difficulties, and was almost abandoned by mid–2006. It was released in January 2007, to critical acclaim and became commercially successful.Critics unanimously praised Karthi's portrayal of a careless village ruffian. Behindwoods said: "He has done away with every trace of sophistication in his body language and even handles the sickle with consummate ease. He looks every inch a hot blooded youngster from some rural part of Tamil Nadu appears seasoned in the romantic scenes ... Uninformed people might not believe that this is the young man's big screen debut. Look out for this guy ... ". Sify said: "It's hard to believe that it is Karthi's debut film as he is just spectacular. His expressions, anger, laughter and anguish are all so realistic that you can feel the fire in him." Rediff called his performance "excellent", and " ... one of the top performances of 2007". Karthi received several accolades for his performance, including the Filmfare Award for Best Actor in Tamil.
2010–2011: Break after Paruthiveeran
In October 2006, Karthi signed his second project under Selvaraghavan's direction, Idhu Maalai Nerathu Mayakkam, which was supposed to be a romance film, featuring Sandhya as the female lead. Karthi's character was a " ... sophisticated upmarket stylish guy ... ". Selvaraghavan abandoned that project and in July 2007, he announced the production of an action adventure film titled Aayirathil Oruvan, with Karthi in the lead role. Filming began later that year and was expected to be completed by February 2008. The producers planned to release it in mid-2008, but production was delayed and filming continued until early 2009. He had agreed to play the lead character in Linguswamy's next film Paiyaa, in September 2007. Because of the slow progress of Aayirathil Oruvan, Paiyaa was postponed several times. He later said that he became anxious because he received several film offers, but could not work on them because he needed to maintain the continuity of his looks. During the filming of Aayirathil Oruvan, producer R.Ravindran complained that Karthi was trying to change his look and move on to Paiyaa before finishing his commitments.Aayirathil Oruvan was released in early 2010. Karthi's portrayal of a chief coolie was often compared to that in his debut film. Sify called Karthi's performance " ... a scream.", and said, "Right from his introduction scene till the end, he is lovable and provides humour.", and that he had " ... made a sensational comeback ... ".In April 2010, Linguswamy's Paiyaa released. A romantic road-trip film, featuring an album by Yuvan Shankar Raja, it was very successful. For the first time, he enacted a character that lives in an urban area. He said that he accepted the film because he desperately wanted to play a cool dude on screen. Karthi's performances in Aayirathil Oruvan and Paiyaa earned him further nominations at the 58th Filmfare Awards South in the Best Actor category. Both films were dubbed into Telugu as Yuganiki Okkadu and Aawara, respectively, and were successful.Karthi's third film in 2010 was Suseenthiran's action thriller Naan Mahaan Alla, in which he played a middle class youth from Chennai whose life is disrupted when his father is targeted by a gang of killers. It received good reviews, was very popular, and Karthi's performances was praised by critics. Sreedhar Pillai wrote for Sify: "[Karthi] nails the character to perfection" ... He is one good reason to see the film." Bhama Devi Ravi of Times of India wrote: " ... what a pleasure to see Karthi deliver his best performance to date ... ". Rediff wrote that "Karthi has simply had a ball ... " and "It's been a long time since you saw an actor who can be as convincing in sadness and rage, as in happiness." Naan Mahaan Alla was dubbed into Telugu and released as Naa Peru Shiva in 2011; it was very successful and earned Karthi some Telugu film offers.Karthi's next film was the action–masala Siruthai (2011), a remake of the 2006 Telugu film Vikramarkudu. He played two roles; a thief and a police officer. Karthi's performances received favourable reviews. Malathi Rangarajan of The Hindu wrote: "Karthi looks and performs better with every film. Siruthai exemplifies the observation". Pavithra Srinivasan of Rediff wrote: "But the film belongs to Rocket Raja (Karthi), the sort of adorable ruffian Tamil cinema has been missing for a while. He picks pockets, slices off handbags, charms women and even bashes (!) them up without a single jolt to his conscience." Despite gaining mixed critical response, the film achieved financial success, becoming one of the highest-grossing Tamil films of 2011. In 2011, Siruthai became Karthi's biggest commercial success, cementing his position in the Tamil film industry. Sify said that Karthi had become " ... one of the hottest stars in Kollywood". He made a special appearance in a song in K. V. Anand's Ko (2011), alongside other prominent actors from Tamil cinema.
2012–present: Career slump and resurgence
In May 2011, Karthi began working on the political comedy film Saguni, directed by Shankar Dayal and featuring him amongst an ensemble cast of supporting actors.

The film was released on Diwali 2013, and received mostly negative reviews from critics, with Behindwoods saying: "Though the laughs are spread across a few moments, when All in All Azhagu Raja is pitted against Rajesh's other wholesome "laughathons" such as OK-OK and Boss Engira Bhaskaran, it falls way short" and Sify saying "The trouble with All in All Azhagu Raja is that it lacks basic story line and took the audiences for granted. The film has no real script to speak of, at best a skeletal plot." His next film was Venkat Prabhu's Biriyani, which was released in December 2013, opening to positive reviews and became a box office success. He also sang the song "Mississippi" under Yuvan Shankar Raja's direction for both the Tamil and Telugu versions of the film. In 2014, Karthi appeared in Pa.

The film received positive reviews. Karthi's performance was also praised, with Baradwaj Rangan of The Hindu stating (in his review of the Tamil version Thozha), "At a time every leading man (including Karthi) seems to be participating in a game-show titled Who Wants To Be The Next Rajinikanth?, here's a simple 'buddy movie' (in the Hollywoodian sense), with no punch dialogues, no action sequences, with just one duet (with Tamannaah, who plays Vikram's secretary; her romance with Seenu is strangely unresolved). We see, all the time, character actors striving to become larger-than-life heroes. For a change, here's a hero scaling himself down to play a life-sized character." Later that year, Karthi appeared in director Gokul's Kaashmora. Though the film received mixed reviews, his performance was praised.Karthi's Kaatru Veliyidai, was directed and produced by Mani Ratnam. The film met with mixed reviews and became a failure.
