The intro to On Cinema has changed frequently over the years.

Being an audio-only, the podcast intro featured just a theme song, Swing City Short, a stock track from iMovie. Episodes would start and end with the track. Starting from Podcast Episode 43: "Dirty Harry", this changed to an unknown track, which according to Gregg was unpopular with fans.^[1] The new track stopped being used after Podcast Episode 49: "Atlas Shrugged".

The most well known intro, and the first to use “Enjoy the Show” as the stock music track. The intro starts with a red curtain, opening up to host Tim Heidecker. Tim proceeds to say various phrases, compiled below. The background behind Tim is different for most episodes. After a few lines, the curtain closes back, only to open again and show the show's logo on a dark blue background.

The recordings of Tim used in the intro were presumably all filmed at once, as Tim is wearing the same outfit in all of them. As some bonus material use clips of frequent guest Gregg Turkington speaking similar lines, it can be inferred that these were also filmed at the same time, but were left out for unknown reasons.

On Cinema at the Cinema Season 6 Episode 1: "Jupiter Ascending" and "The Spongebob Movie" On Cinema at the Cinema Season 6 Episode 2: "Fifty Shades of Grey" and "Kingsman: The Secret Service"

Same as the previous intro, but it features new lines from Tim, as well as a few casino references, given that this is “lucky” season 7. On Cinema at the Cinema Season 7 Episode 8: "Autobahn" and "Scout's Guide to the Zombie Apocalypse"'s intro changes the theme to Dekkar's ”Empty Bottle“, only to change back by s07e10.

The intro gets a big change as the new season takes place at the Victorville Film Center. Gregg contributes most of the new lines on location at the Center, while Tim's past green-screened lines are reused. Mark Proksch, a cashier at the Victorville Film Center, appears in some of the intros. The intro at the end now refers to the show as Tim Heidecker's On Cinema at the Cinema, with Gregg also saying this with some of his lines.
