With less than a month before Gotham returns to debut the back half of Season 4, Fox has released a new preview that gives fans a recap of the first half of this season, along with a sneak peek at future episodes. The five-minute clip begins with the return of Jerome (Cameron Monaghan), teasing his Joker turn. Fox hasn't issued a renewal for Gotham at this point in time, and while it very well could return, a recent ratings dip could prove to be trouble for the show.

We reported in October that the Gotham Season 4 ratings hit a series low, which is certainly not a good sign for the series return. There is no concrete indication as to whether or not the show will be back for Season 5, but if the show posts a ratings increase in the back half of the season, it's certainly possible that Fox could renew the show. Still, there is no indication as of yet as to when Fox could make the decision on whether or not to renew the series set within the DC Universe.

Season 4 of Gotham witnesses the emergence of the criminal landscape for which Gotham City is best known, with Jim Gordon (Ben McKenzie) and Harvey Bullock (Donal Logue) at the forefront of the fight against the most depraved and unhinged villains. As the citizens of Gotham City fight for normalcy, a new hero begins to rise. Bruce Wayne (David Mazouz), after completing his training with Temple Shaman (guest star Raymond J. Barry) and Ra's al Ghul (Alexander Siddig), has decided that he is responsible for the city's well-being. With the help of his ever-faithful butler Alfred Pennyworth (Sean Pertwee) and quiet support of Lucius Fox (Chris Chalk), he will step into this role, all while building up his public persona of carefree socialite to avoid any suspicion among Gotham's citizens.

It was revealed earlier this season that Drew Powell's Butch Gilzean character is actually Solomon Grundy, although it isn't known what other surprises Gotham may have in store for the fans. Gotham is based upon the characters from DC Comics and is produced by Warner Bros. Television. Executive producer Bruno Heller wrote the pilot, which was directed and executive-produced by Emmy Award nominee Danny Cannon. John Stephens serves as an executive producer and showrunner on the series. Take a look at the new trailer below, courtesy of Fox YouTube.
