“Children’s Hospital” star Rob Corddry is in talks to join Mark Wahlberg, Dwayne Johnson and Ed Harris in Michael Bay’s low-budget Paramount pic “Pain and Gain.”Based on a true story first told in an article from the Miami New Times, film follows a group of bodybuilders who engaged in a campaign of kidnapping, extortion and murder in Florida. Corddry will play John Mese, a former competitive bodybuilder who now owns the gym where Wahlberg’s character works as a personal trainer. His past as an accountant and notary makes him a valuable though unwilling member of Wahlberg’s scheme. Bay is producing with Donald De Line and Ian Bryce. “Captain America” scribes Christopher Markus and Stephen McFeely wrote the script. Production is expected to begin in early spring. Corddry has a busy year of red carpets ahead of him, as he stars in Summit’s zombie pic “Warm Bodies,” and co-stars in The Weinstein Company’s comedy “Butter,” as well as “Seeking a Friend for the End of the World,” which Focus releases June 22. Adult Swim will begin airing the fourth season of “Children’s Hospital” this summer. Corddry is repped by WME, Principato-Young Entertainment and attorney Ken Richman.
