TIL that Tom Cruise's character in Tropic Thunder is based on a real guy; he was the producer of The Matrix and co-invented ultimate frisbee

You take the blue pill, you wake up on your bed, and believe whatever you want to believe.

You take the red pill, you take a big step back, and literally FUCK YOUR OWN FACE.

Joel Silver - Wikipedia

That was some great acting on his part for that character

I still believe it is the best performance of Tom Cruise’s career.

Why?

Because at the first time I saw the movie, I never recognized him

Same here. It wasn’t until the credits rolled I was like WHAT?!
I agree. He is one of those actors who always plays himself in whatever film he’s in.
