Washington, Jan 28 : Hollywood actor Josh Brolin was left embarrassed when his pants ripped open while shooting his first scene with co-star Russell Crowe on the set of `American Gangster'.

Brolin admits he was nervy about acting opposite Oscar winner Crowe in the 2007 film, and the untimely wardrobe malfunction made things worse.

"I was a little plumper than I wanted to be. I justified it that the character''s tough and he needs to be plumper. I came to the set they put the wardrobe on me and it was tight," Contactmusic quoted him as saying.

"I just get through my nerves with Russell, and improvise a little bit. I grab a chair and when I sat down the ass of my pants ripped right open.

"Usually, that''s a great ice breaker but I did the worst acting I''ve ever done in my life. I was shaking, I was nervous," he added.

The 40 year old actor revealed that he feared the accident would cost him his job but was amazed when director Ridley Scott appreciated his performance.

"I got back to my trailer, took off my pants, gave them to wardrobe and went to my trailer waiting to get fired.

"I finally got a knock on the door and Ridley says ''Josh, I don''t know what you''re doing, but you''re bringing an incredible vulnerability to this role.''

"It was remarkable... I don''t wear pants anymore," he added. (ANI)
