Watch: Matt Damon And Lilly Collins Meet Daniele Rizzo As "Sam" And The Wolfster, Respectively

It's ain't easy being The Wolfster. Or "Sam," for that matter. Our friend, actor and comedian Daniele Rizzo, likes to dress up in full makeup and costume for his interviews with actors and filmmakers promoting their latest releases in Europe.

And so he dressed up as "Sam" for Matt Damon, Sharlto Copley, and Neill Blomkamp (Elysium). For Lilly Collins and Jamie Campbell Blower (The Mortal Instruments), he appeared as "Wolfgang, aka The Wolfster."

I always love the spontaneous reactions of the interview subjects when they see Daniele come walking through the door. Damon has fun with it -- note what happens near the end when he's asked if he has any message for the future Jimmy Kimmel -- and so does Copley, who turns savagely into character on a moment's notice. Blomkamp goes along with it and then answers a more serious question.

My favorite moment of both videos, though, is when "The Wolfster" gets Ms. Collins to sing along with his song "Shadow Hunters," sung to the tune of "Ghostbusters."

The videos are definitely worth a look for those who enjoy decidedly off-beat celeb interviews. You can watch them both below.
