Jason David Frank (born September 4, 1973) is an American actor and professional mixed martial artist. He is most notable for his portrayal of Tommy Oliver, the original Green and White Rangers in multiple seasons of Power Rangers.
Frank originally auditioned for the role of Jason Lee Scott, the Red Ranger, but lost the role to Austin St. John. He auditioned again in 1993, and was cast in the role of Tommy Oliver, the Green Ranger.
Frank was supposed to be the lead character Adam Steele in VR Troopers (originally called "Cybertron") and shot a pilot episode before being called back to Power Rangers. According to both Frank and Brad Hawkins, Hawkins' character was to replace Tommy Oliver originally as the White Ranger on Power Rangers. However, due to Tommy Oliver's popularity with Ranger fans, Frank was brought back, with Tommy Oliver becoming the White Ranger. Hawkins would take over on VR Troopers. The character Adam Steele was renamed Ryan Steele.
