A behind-the-scenes video shows Cameron Monaghan's transformation into the Joker for the Gotham series finale. Gotham concluded last year, running for five seasons on FOX network. Although starting out as a crime drama with Jim Gordon at the center, it became a Batman prequel, showing young Bruce Wayne's transformation into the iconic caped crusader.

Gotham was one of the more intriguing shows based on a comic book property. Many iconic Batman antagonists were featured. Penguin and Riddler were the two most prominent, but characters like Poison Ivy, Mr. Freeze, and even the Ventriloquist appeared. Perhaps the most acclaimed aspect of the program was Monaghan's take on the Joker. Gotham's Joker can be a rather odd thing to discuss. Monaghan played a character called Jerome, who exhibited many of the Joker's traits. However, he would end up not being the Joker, instead exposing his brother, Jeremiah, to the chemicals. Jeremiah would be a central antagonist until the show's end. In the timeskip, Jeremiah wears the iconic purple suit. Although the show didn't use the name Joker, for all intents and purposes, this was the character, although the producers never outright confirmed it.

In a behind-the-scenes video from Ben Bornstein, Gotham's Cameron Monaghan is shown in a timelapse becoming the Joker. Check it out below.

In Gotham's final episode, there is a 10-year timeskip. Jeremiah was seemingly brain dead all this time. However, it was just a ruse, and he quickly claims dominance. He nearly kills Jim's daughter, but Batman arrives, and defeats Jeremiah with a batarang. Although brief, it did give fans something no one thought possible in the first season: an encounter between Batman and Joker.

Monaghan's performances in Gotham, namely Jerome, has left an impact on viewers. One may find fans even favorably comparing Jerome to Heath Ledger's portrayal of the Joker in The Dark Knight. Mark Hamill, the most iconic voice of the Joker, praised Monaghan's performance as Jerome. While many fans likely thought it was pointless to introduce Jeremiah, the character did bring other Joker traits to the table. Jerome was insane, but Jeremiah was calculated. Jeremiah's evolution in the series finale arguably merged both personas into a single, perfect version of the character for the world of Gotham. It's a shame Gotham concluded, because a season focusing on the world after the timeskip could have provided more memorable encounters between Bruce, Jeremiah, and the rest of the characters. At the very least, though probably not very likely to happen, the cast is open to a revival if everyone returned.
