Sellars is the CEO of the corporation behind RoboCop.
Production is scheduled to begin next month in time for an Aug 9, 2013 release. Keaton joins previously announced Joel Kinnaman, Gary Oldman and Samuel L Jackson. José Padilha directs.
“Michael is the final addition to the amazing cast we have assembled for this film and it is so great to have the last puzzle piece in place,” Padilha said.
“It is thrilling that everything has come together to bring this innovative new vision of RoboCop to life. We’ve got a great script, a great cast, some killer ED-209’s and I can’t wait to get Alex Murphy back on the streets.”
