Kaley Cuoco will star in a wedding comedy with Kevin Hart, Josh Gad

Kaley Cuoco will play the self-centered fiancée of Gad in the movie, which will be directed by 'The Break-Up' writer Jeremy Garelick. Kaley Cuoco currently stars on the sitcom 'The Big Bang Theory.'

“Dredd” star Olivia Thirlby and Kaley Cuoco are set to join Kevin Hart and Josh Gad in the untitled comedy that Jeremy Garelick will direct for Screen Gems and Miramax, an individual familiar with the project has told TheWrap.

Hart stars as Jimmy, who provides best-man services for socially challenged grooms who have no close friends willing to stand by them on their wedding day.

Gad will play Doug, a groom-to-be who fabricates not just his best man, but his nine groomsmen as well. Together they must carry out a charade that is designed to make Doug look his best but threatens to destroy everything if it fails.

Kaley Cuoco will play Gad’s self-centered fiancee, while Affion Crockett will play one of the fake groomsmen.

Thirlby will play Cuoco’s sister who develops a crush on Hart’s character.

The project, which is currently untitled, was formerly known as “Best Man Inc.” when it was developed at Miramax. Garelick wrote the script with Jay Lavender.

Cuoco stars on the CBS sitcom "The Big Bang Theory." Thirlby recently appeared in “Dredd,” “Being Flynn” and the indie drama “Nobody Walks.” She recently wrapped the indies “Red Knot” with Vincent Kartheiser and “5 to 7″ with Anton Yelchin.
