The show is about a wheelchair-bound police detective, Robert T. Ironside, played by Blair Underwood. Trivia side note: hardcore fans know that Bruce Lee guest starred on an episode of the original Ironside, "Tagged For Murder," in 1967. Here's a cool vintage video clip of Bruce in action.
Choi is perhaps best known as Jim Morita, one of the Howling Commandos in 2011's Captain America: The First Avenger (or maybe you remember him for his awesome William Shatner impression in that one Priceline commercial). In Ironside, he will play Captain Ed Rollins, Ironside's supervisor:
Written by Mike Caleo and directed by Peter Horton, it centers on Robert T. Ironside (Blair Underwood), a tough, sexy and acerbic police detective relegated to a wheelchair after a shooting who is hardly limited by his disability as he pushes and prods his hand-picked team to solve the most difficult cases. Choi will play Captain Ed Rollins, Ironside’s supervisor. Despite their push/pull relationship Ed and Ironside have a tremendous amount of respect and admiration for each other.Cool. Just based on the name, it looks like the character wasn't necessarily written with an Asian American actor in mind. I like that. I hope the show gets picked up so we can see Kenneth in action.
According to Deadline, Kenneth Choi will also reprise his role as Jim Morita in the upcoming sequel Captain American: The Winter Soldier, but I haven't been able to find anything else confirming his return. Hope we'll get to see him kicking some ass in that movie too.
