The cast of the "Grand Theft Auto" movie is growing. New reports suggest that Daniel Radcliffe, the lead in the upcoming drama about one of the men behind the popular video game, may have found his antagonist co-star. The British actor is set to portray Rockstar Games co-founder and president Sam Houser, who faced off against Miami-based attorney Jack Thompson in a fight over the game's violent content. The Hollywood Reporter says Bill Paxton is in talks to join the cast as Thompson.

Thompson was a staunch anti-violence crusader, filing court cases citing the "glorification of violence" by video games such as“Grand Theft Auto” and “Mortal Combat.” He got so carried away that the Florida Bar Association disbarred him in 2008 for his inappropriate conduct during the court proceedings in the "GTA" case.

Radcliffe, who’s been exploring radically different roles since his “Harry Potter” days, will star in the horror film “Victor Frankenstein” later this year. Last year, he tried romantic comedy with Zoe Kazan in “What If” and appeared in the dark fantasy “Horns.” He also has a small cameo in the upcoming Judd Apatow film “Trainwreck.”

As for Paxton, he can be seen later this year in the movies “Term Life” and “Pixies.” Audiences can also catch him in the upcoming mini-series “Texas Rising." Last year, Paxton appeared in the critically acclaimed movies “Edge of Tomorrow” and “Nightcrawler,” with a recurring stint on ABC’s “Agents of S.H.I.E.L.D.” The “Grand Theft Auto” project won’t be Paxton’s first foray into video games, as he recently appeared on the latest “Call of Duty” sequel. 

Based on David Kushner’s “Jacked: The Outlaw Story of Grand Theft Auto,” the BBC Film production of "Grand Theft Auto" is helmed by Owen Harris and is scheduled to begin filming April 20.
