It was quite involved.

But every morning, bright and early, I shared a makeup trailer with Michael Rooker.

Michael Rooker is like the Merle Haggard of the acting world.

Never a dull moment.

Never a dull story.

Ive been a huge fan of his sinceHenry: Portrait of a Serial Killer.

I dont think theres anyone like him.

I think hes singular.

I would pay money to sit next to him and get into makeup.

Dont tell Marvel that!

Hes a very loud individual who enjoys pushing people around.

What was the audition process like?The audition process was fairly concise.

I put myself on tape and that was the end of the story.

What was James Gunn like to work with?James Gunn runs his set like a 12-year-olds birthday party.

Every day, he is so excited to come to work.

He almost appears surprised that someone is still allowing him to live out his childhood fantasies.

Its kind of infectious.

It makes the days fly by.

Taserface has some interesting origins in the comics, so we shall see what his fate holds.

I dont want to make any promises, but I think its better than the first one.

I would say its more fleshed out, just simply by the fact therewasa first one.
