Many comedic actors have successfully made the jump to action star, but they've usually had other talents that assisted in the transition. Few questioned when Eddie Murphy or Bruce Willis (remember, he started out on "Moonlighting") transitioned to kick-ass leading man. Seth Rogen would not fall into that category. In fact, many questioned when Sony Pictures agreed to let him star as the title character in their big screen "Green Hornet" adaptation. The usually rotund Rogen took the naysayers seriously and lost 30 pounds for the role getting in the best shape of his life. The "Knocked Up" star had the last laugh when "Hornet" grossed over $225 million worldwide. Well, he sort of did. You don't hear anyone clamoring for a sequel do you?
