Hart came to prominence from his guest appearance in Undeclared.
He made his film debut in the film Paper Soldiers.
Hart then gained further recognition from his other films such as the Scary Movie franchise, Soul Plane, The 40-Year-Old Virgin, Death at a Funeral, and Little Fockers.
He turned down a role in the 2008 film Tropic Thunder because the character is gay, citing his own "insecurities".

He played Doug in the film The Five-Year Engagement (2012) and appeared in Think Like a Man which was a box office success.
He also appeared in the sequel.
He had a cameo as himself in This Is the End.
In 2013, Hart played a boxing promoter in Grudge Match and appeared in Exit Strategy as Mannequin Head Man.
He also appeared in 35 and Ticking.

In 2014, Hart starred as Ben in Ride Along, opposite Ice Cube.
The film received generally negative reviews from critics, but was a major box office success.
Hart returned in the sequel, Ride Along 2, which was released on January 15, 2016.

In 2013, Hart co-created Real Husbands of Hollywood with Chris Spencer.
The show follows Hart along with other married celebrities (each playing a comical fictionalized version of themselves) within the series including: Boris Kodjoe, Nelly, Duane Martin, J.B. Smoove, Nick Cannon, and Robin Thicke.
Thicke didn't return for the second season due to his music career, though Hart has stated that the door is open for Thicke to return.
The series is intentionally filmed in a style similar to Bravo's The Real Housewives.
Episodes often hinge on the "real" Kevin Hart's desperately unsuccessful attempts to climb Hollywood's celebrity social ladder (which always backfire in humiliating ways), and the character's barely-hidden jealousy of his more successful celebrity friends.
A sneak peek was shown as a segment during the 2012 BET Awards and the official promo was released in October 2012.
