Episode 8 of “Castle” was a nail-biter, with everyone on edge to see if Esposito would escape the subway with his life after an activist took the cop’s train hostage. The ABC series’ next episode, “Last Action Hero,” looks like a lot more fun as Castle (Nathan Fillion) gets to meet one his favorite actors – well, sort of.

According to the synopsis, Castle and Beckett (Stana Katic) are on a new case when Castle discovers that the murder victim was the star of his favorite action movie from the 1980s. With the help of another action star, Brock Harmon (guest star Ted McGinley), the couple investigates the secret past of the former action star in the hopes of finding his killer. From the promo for the new episode, it seems clear that Castle is having fun delving into the world of action movies, while Beckett, on the other hand, is less than enthused.

Watch the promo for episode 9 below:

Fans, though, might be hoping for some more movement on the Esposito and Lanie (Tamala Jones) front after the last episode. Lanie was seriously shaken up after seeing Esposito caught in a life or death scenario. Plus, the other cop with Esposito on the train pointed out that he mouthed her name before making his move on the killer. The on-again, off-again couple shared a tender moment at the end of the episode after reuniting. Is there more to come?

Will Esposito and Lanie get together for real? And what will happen when Castle enters the world of 1980s action movies? Fans will have to tune in to find out. “Castle” airs on Mondays at 10 p.m. EST on ABC.
