[Kathy]

I know how much you love him so...

Keanu Reeves?

[Sanuye]

No  , I would have been too much predictable.

I explored Hollywood when I was a teenager and I found a very good teacher
Before my last year movie, I played in 5 other movies with the same director
Once I worked in a very clean cubicle
I was trained to be a cop

It seems I don't need a tin foil hat after all...

I explored Hollywood when I was a teenager and I found a very good teacher
Before my last year movie, I played in 5 other movies with the same director
Once I worked in a very clean cubicle
I was trained to be a cop...
and later I became an interpol agent chasing an arms dealer

[Najemikon]

Ethan Hawke?

[DJ Doena]

OF COURSE! 

Clean Cubicle -> Gattaca.....


But after the last hint I would have got it too, I just watched Lord of War.

I explored Hollywood when I was a teenager (Explorers, 1985) and I found a very good teacher (Dead Poets Society, 1989)
Before my last year movie (Fast Food Nation, 2006), I played in 5 other movies with the same director (Richard Linklater: Before Sunrise, The Newton Boys, Waking life, Tape, Before Sunset)
Once I worked in a very clean cubicle (Gattaca)
I was trained to be a cop... (Training Day, 2001)
and later I became an interpol agent chasing an arms dealer (Lord of War, 2005)

Warren Beatty?

Totally random.

[Najemikon]

Not that random, Sailor. In fact, you are absolutely ... wrong. Wronger than a wrong thing that is never right. 

"In a defining role, I could have been mistaken for a cartoon character."
"It really bugs me that you couldn't connect me with the first clue."
"It'll fall on deaf ears, but I'm sorry about my attitude in the last clue. Even though I can't see you I want to be your friend."

[Kathy]

You are too tricky for me - I couldn't even cheat if I wanted too, I wouldn't know where to start!

"It'll fall on deaf ears, but I'm sorry about my attitude in the last clue. Even though I can't see you I want to be your friend."
"That's ok. Just keep guessing and talking amongst yourselves. I like to just listen to people talking."

Bob Hoskins?
