Help me find a very specific disney movie

119 views#1 MoviesDisney old films

When i was a bit younger, i remember watching this movie a few times but now that i’m looking for it i cannot find it.
It’s quite old i think because it starts black and white with a guy sitting in a pool with his wife. A little later he visits disney studios, i don’t remember why. And he pretty much takes a tour of the place while getting chased by some guy that works there that he doesn’t want to talk to. A scene i specifically remember is when he watches the people making the sounds for an animation of a train. About halfway through, the movie turns to colour. I don’t remember much else about the movie except that it may have dragon in the title but i wouldn’t count on it.
Any help would be appreciated thanks!
