The trailer, which clocks in at over two minutes, is a look at the rest of the episodes filmed so far, not just the next episode, and is a bit like the bigger-picture trailers that you usually get at the start of the season.
We also get a look at the conflict between the different elements of organized crime in Gotham and a character who looks to be Professor Pyg.
You can see the video below.
A new episode of Gotham will air tonight at 8 p.m. ET/PT on Fox.
