They say if you want to get something done, you should give the task to a person who's already busy. Maybe that explains the deal announced earlier Wednesday for Robert Downey Jr. to possibly star in a newly-launched 'Perry Mason' movie franchise. For those keeping score at home, this would be the actor's third active franchise, after 'Iron Man' and 'Sherlock Holmes.' Which made us wonder: does RDJ really have time to star in three huge blockbuster franchises at once? Is he spreading himself too thin? Should we applaud him for his ambitious scheduling or disdain him for monopolizing the limited pool of franchise material out there for fortysomething actors?
