I find that 'Ghostbusters' and 'Alien' actually have a lot in common in that they're both so naturalistic in the performances. It feels like people you could be hanging out with right now in this room, yet they're on a spaceship or killing ghosts. But the way they talk is never heightened or otherwordly.

What 'SNL' taught me that was useful on 'The Watch' was, only put in bad words if they can get a laugh - there was no need for swear words and beeps in places that weren't necessary. Those beeps should only be in there when they mean something and it's important to the joke.

Nothing is better than the moment you have Michael Bolton dressed as Forrest Gump and you see it in action.

The Watch' is first and foremost a comedy, but since I got to shoot the film using elements from the sci-fi genre, I wanted to make sure the alien didn't look goofy. I got to make a real alien that looks dangerous. That was a big plus for me because I got to do something really fun and cool.
