As we reported earlier this week, Castle will be going retro when it returns for Season 6. Castle, Ryan, and Esposito will be investigating a murder on the set of a reunion movie for a popular ‘90s sitcom, 2 Cool For School.

The show is based off of Saved By the Bell, and tragedy of all tragedies, their version of Screech is murdered! Now TV Guide reports that soap opera star Antonio Sabato Jr. will guest star on Castle as Ramon Russo, who had a big role in the sitcom.

Antonio looks a little bit evil, but if five full seasons of Castle have taught us anything, the culprit is rarely who you think it is at first.

The actor has had roles on General Hospital and The Bold and the Beautiful, so we’re sure he’d get along well with Martha Rogers.

Is Antonio a good fit for Castle? Tell us your thoughts below!
