Bill Murray? He's listed in the credits as himself.

So strange that you review this film NOW, seeing as it came out last year and I just watched it for the first time yesterday. You guys always end up posting articles that are congruent with my current taste even on a flavor-of-the-week-type basis. I feel like I should work for you. Visioneers was clever. I put it on as something to fall asleep to because I was previously aware of how light on dialogue it was, but it ended up holding my interest even at 5 in the morning, but alas if you didn't know or hear about this movie already it's probably not for you.
