re: who are the top 5 biggest pricks/coolest bros in hollywood

Nobody would want to have a drink with Stiller .... a notorious jerk. I have never worked with him, but have worked somewhat closely with:

Ryan Phillipe - super bro, but super nice and passionate about his work
Jon Hamm - very serious actor ... attended a small party when he was still drinking. Was fun at the party
Ed Helms - one of the most genuine people in the business
Owen Wilson - aloof and guarded, but likes to get after it
Zac Efron - very genuine and nice guy
Chris Hemsworth - extremely down to earth and nice

I hear good things about Ryan Reynolds and Vince is apparently hit or miss depending on how much he is partying.
