Wiig wrote the comedy with her 'Bridesmaids' partner, Annie Mumolo.

Jamie Dornan is joining comedy Barb and Star Go to Vista Del Mar from Bridesmaids duo Kristen Wiig and Annie Mumolo.

Wiig and Mumolo star as best friends Barb and Star, who leave their small Midwestern town for the first time to go on vacation in Vista Del Mar, Florida, where they soon find themselves tangled up in a villain's plot to kill everyone in town. 

Dornan will play Edgar, a lovelorn spy who gets caught between the forces of good and evil.

Wiig and Mumolo co-wrote the script for the Lionsgate pic, which will be directed by Josh Greenbaum and is slated for a 2020 release.

Gloria Sanchez Productions — the female-focused production banner founded and led by Jessica Elbaum, Will Ferrell and Adam McKay — will produce, along with Wiig and Mumolo. 

Dornan, who is repped by UTA, the U.K.'s Troika and Sloane Offer, will next be seen in Drake Doremus' new movie, starring opposite Shailene Woodley and Sebastian Stan. He will then star opposite Anthony Mackie in Justin Benson and Aaron Moorhead's Synchronic, and will begin production on John Patrick Shanley's Wild Mountain Thyme.
