It's been 15 years since "Dodgeball: A True Underdog Story" hit theaters are proved that you really can make an underdog sports movie about any sport. Get back in fighting shape (and avoid those wrenches) by learning more about the making of "Dodgeball" and that sequel we may or may not ever see.

1. Writer Rawson Marshall Thurber wrote the screenplay with Ben Stiller, Vince Vaughn and Justin Long specifically in mind for the roles of Peter, White and Justin, respectively. Fortunately, all three signed on.

2. While most of the wrenches in the iconic wrench-throwing sequence were made of rubber, one of them was actually real. Long was injured when it hit him in the eyebrow.

3. The filming process was hard on the equipment as well as the actors. Stiller reportedly broke three different cameras filming a single scene.

4.Patton Oswalt provided voiceover work for the film, dubbing over Ben Stiller in one particularly risque scene and voicing the video store clerk at the beginning of the film.

5. The movie apparently takes place in 1993. This is revealed thanks to White's before and after video, which dates his "six years and six hundred pounds ago..." photo as 1987.

6. "Dodgeball" delivers a subtle homage to the G.I. Joe franchise via the team names of the rival gyms, "The Average Joes" and "The Purple Cobras."

7. The "Dodgeball Unrated" DVD contains a bizarre director's commentary featuring Stiller arguing with his fellow actors for roughly 40 minutes, after which the track is replaced by the commentary to "There's Something About Mary."

8. ESPN paid homage to "Dodgeball' in 2017 by airing a one-day "ESPN 8: The Ocho" marathon covering unusual, off-kilter sporting events.

9. 20th Century Fox announced a sequel to "Dodgeball" in 2013, though no further updates have been made. However, the cast did reunite in 2017 for a YouTube campaign geared toward a charity dodgeball tournament.
