I like Wahlberg better - I think he has some potential to be really funny. His role in Date Night with Steve Carrell and Tina Fey was effing hilarious. I don't know if I can say the same for Bruce Willis.
I just watched that movie recently. I didn't Wahlberg was particularly funny. I thought it was really how Carrell and Fey responded to him that was funny.
I wouldn't consider Marky Mark's first single to be a failure, that video gained huge popularity. Than his second single wildside had plenty of play too. It was just short lived but than he got into other stuff that continued his success.
