After last week’s tragic shooting death of his brother, work is probably the last thing on Mark Ruffalo’s mind.

Now comes word that the You Can Count On Me actor has dropped out of what was supposed to be his next job, the indie dramedy Greenburg. According to the Hollywood Reporter, Ruffalo will be replaced by Ben Stiller, who will make a rare dramatic turn in the Noah Baumbach-helmed project.

No official reason has been given for Ruffalo’s departure, but considering the circumstances, it’s easy to understand what his motivation might be.

Beverly Hills police continue to investigate whether his brother, Scott Ruffalo, died from a gunshot wound to the head after playing Russian roulette. An autopsy is scheduled to be performed later today.

Ruffalo’s not the only major departure from Greenburg. Amy Adams was supposed to costar, but she, too, has decided to pass, and a search is under way for her replacement.
