In the waiting room of the dentist office, you can see a Buzz Lightyear action figure lying on the floor.

While the credits are rolling you see most of the characters swim onscreen. Stay long enough and you'll see Mike from Monster's Inc. swim across with a scuba mask and fins.

In the first scene the tank has become dirty, you can see the dentist outside talking to a kid in the dentist chair, he says to the kid, 'Little David Reynolds...', which is the name of one of those who have done the screenplay of the film. The name appears in the ending credits before the Cast.

Stay past the credits and you will see the vicious Angler fish get eaten by the tiny little fish that ran away from the shark meeting.

When they show the kid waiting in the waiting room he is reading a comic. The person on the cover is Mr. Incredible, who is from the Disney/Pixar movie The Incredibles.

The 3 tiki heads in the fish tank are actually some of Finding Nemo's animators and directors. (Explained on Disk 1 of the DVD.)

If you look closely when Nigel hits the dentist's window, you can see Boo's mobile from Monsters, Inc. attached to the dentist's ceiling.

The Mermaid from the short film "Knick Knack" is seen inside the fish tank.

The voice of Crush, the sea turtle dude, is Andrew Stanton, the writer and director.

When we see the close up of the whale's head while he is blowing bubbles you can see they spell the word SEX or SFX depending how you look at it. Very similar to what they did in The Lion King.

This is just an interesting anecdote: In an Australian newspaper, some poor irate viewer of 'Finding Nemo' wrote a long and indignant letter abusing the creators of this movie for using AMERICAN pelicans rather than AUSTRALIAN pelicans (noticeable only for the fact that Aussie pelicans don't have brown feathers and Nigel does). This anonymous person was 'disappointed that the creators couldn't even make the effort to use native Australian fauna'. The editor of the paper replied to the letter thusly: 'Thank you for your heartfelt contribution. We also noticed a glaring mistake in 'Finding Nemo': Fish can't talk.' However, this is in no way meant to offend the person who has already pointed out this mistake on this site.

Great White shark in the rehab group is named Bruce, the same name Steven Spielberg called the mechanical shark in Jaws. Pixar is known for crediting great filmmakers from the past, in their movies.

If you look closely when they show the baggie go out the window during Gill's escape plan you can see the Pizza Planet Truck drive by. The second car after the pizza planet truck is from the movie "Cars" which is out in 2006.

Until June 2004, it was both the highest-grossing animated and CGI-animated film in North American history before "Shrek 2" broke these records.

A tip of the hat (or two) is given to the first Disney underwater flick, 20,000 Leagues Under the Sea. The title character Nemo was the name of the captain from 'Leagues'. The song 'Whale of a Tale' was sung in both movies.

Random bit of trivia: In the Latin language, nemo means "No name".

In early stages of production, a slightly more dramatic approach was to be taken on the film, and to that end William H. Macy was hired as the voice of Marlin the clownfish. However, after a couple of weeks of recording sessions, the dramatic approach was scrapped, and William H. Macy was replaced by Albert Brooks, who plays Marlin in the film.

John Ratzenberger, who does the voices of the school of fish - who do the impressions for Dory, has done a voice in every Disney-Pixar movie. He has done Hamm in Toy Story and Toy Story 2, P.T. Flea in A Bug's Life, the Yeti in Monsters, Inc., and Underminer in The Incredibles.

There's a scene where Crush the turtle is describing how they found Marlin and Dory. Well, that scene looks very similar to one in The Little Mermaid, where Flounder is describing how he and Ariel escape from the shark attack in the ship.

One of the boats in Sydney Harbor is named "For the Birds;" a Pixar short. Also, other boats in the harbor are named after the people who helped make the film.
