- Direct-to-Video: What this movie was originally intended to be released as.
- Dueling Movies: The movie was made as a direct response to the massive box office success of The Rugrats Movie that same year, both films being based off of the highly successful frontrunners of each network at the time. Unsurprisingly, that film performed significantly better.
- Fan Nickname: Doug's Only Movie, as a sequel was never made nor in production.
- Franchise Killer: The movie is often erroneously believed to be this for Doug, as while the movie had a decent box office gross, it was massacred by the critics. In reality, the show lasted for fourteen more episodes before ending due to Disney's 65-episode policy. Merchandise only ended production after the closure of Doug Live!.
- Keep Circulating the Tapes: The movie was released on video in September 1999 and was quietly re-issued in mid-2000, and only on VHS, even though Disney had entered the DVD market by then.note The film went out of print around 2001, when Doug was removed from ABC's lineup. For a while, the film wasn't available, aside from being shown on Toon Disney often. Then, in 2011, the film was put onto iTunes (rental only) and Amazon Instant Video. Thirteen years after the video release, Disney finally released the movie on DVD in 2012, though with two drawbacks - the first being that it was exclusive to the Disney Movie Club (which is US only), and the second being that instead of remastering the film, Disney used the TV edit master, with various fade out / fade ins in between various scenes, and speeding up the credits, featuring only half of "Someone Like Me." Thus, if you want the closest representation of the original theatrical presentation, you have no choice but to keep your VCR!
- No Export for You: The 2012 DVD, being an exclusive to the Disney Movie Club, is not available outside of the United States.
- Stillborn Franchise: Doug's 1st Movie was also his last. The two reasons why a sequel was never planned could possibly contribute to the movie not being as successful as planned, and the other being that Doug wrapped shortly after the movie was released (the movie came out in March 1999; the last episode premiered in June) and Disney wanted to focus more on Recess at the time.
- What Could Have Been:
- Originally, Roger's subplot would have been about him having a crush on Herman in his girl disguise. This subplot was kept in the novelization.
- In 1993, 20th Century Fox was originally going to make movies based on the first three Nicktoons. The Ren & Stimpy Show never got the feature film they announced, and The Rugrats Movie was released in 1998 by Paramount. What the original plot consisted of is unknown.
