This was the night Farrell filmed the show’s shocking finale, which sees his character Oswald Cobb murder beloved mentee Victor Aguilar (Rhenzy Feliz).

"The Penguin" finale finds Colin Farrell's gangster ascending to power in Gotham City and losing "any semblance of decency" he had left, Farrell says.

Despite Farrell's willingness to suit up again, let's not count penguins before they hatch. Right now, there are no plans for "The Penguin" season 2 — at least, no official announcements have been made by HBO at this time. With the finale's seemingly tidy wrap-up of the series, it may not even make sense to continue with another installment.
