I Did Not Know That shared little-known information that, early in his career, John Travolta had auditioned for the role of Arthur “Fonzie” Fonzarelli in the 1970s sitcom series Happy Days. Originally, former Monkee Micky Dolenz was considered for the role, but he was too tall compared to Ron Howard. Travolta wanted the role but he didn’t want to go blond, which was an early requirement for the role.
Travolta said that when he read the script Fonzie was described as having blonde hair. He said he kept wondering if he’d have to dye his hair blonde if he go the part and he sounded like he wasn’t real crazy about that idea. He didn’t have to worry about it long because he didn’t get the part.
Eventually, Henry Winkler got the job, dark hair and all.
Travolta said that when happy days eventually came on the air and became a hit he saw the fawns had dark hair and thought i could have been the Fonz after all.
