CGI is making their attempts slicker, but Hollywood is constantly derailed in it’s efforts by it’s own self.

Clearly Reagan would not have been pumping his own gas, not in a tuxedo anyway. Fake.

According to conservative critics of the documentary, not once in the entire film did this person, clearly an actor, ever don a cowboy hat.

They’ve had a lot more success there. Bush Sr. has been dead for almost 2 years now, conservatives know it, but Robin Williams refuses to break character, so nothing can be proven conclusively.
