3. Mark Wahlberg - Jack Twist (Brokeback Mountain)
Mark Wahlberg has many strengths as an actor, but perhaps playing a self confessed gay man isn't one of them. He himself admitted that he was a bit "creeped out" by the whole gay theme running through "Brokeback Mountain", which was most probably the reason behind him declining the role. Yes, Wahlberg was the first choice for the role of Jack Twist in Ang Lee's homosexual spectacle, however, after he vehemently vetoed the character and the film, the role ended up going to Jake Gyllenhaal, an actor who seems more confident in his own manliness that he can play a gay man without embarrassment. Having seen the critical and commercial success of Brokeback Mountain, Wahlberg might be slightly regretting his immaturity in declining the role, and to add salt to Wahlberg's wounds, Gyllenhaal recieved an Oscar nomination for his stunning performance. After this embarassing saga, it seems that Wahlberg is never going to make it as a world class actor if he can't handle with the variety of roles that are going to come his way.
