How did the Yu-Gi-Oh anime differ from the manga? I was wondering, how does the Yu-Gi-Oh manga differ from the anime? If someone enjoyed the anime would they like the manga?  

And were there ever any Yu-Gi-Oh movies?
The manga starts with Yugi and the soul inhabiting the enigma being involved in many different disputes on many different kinds of games: from card games, tabletop games, electronic games, video games, lots of gambling and small crimes too.

Then, the card game created for the manga starts being the center piece of the story, with clear rules being developed and all.

The story centered on the card game is the one they adapted into the anime, after removing and altering much of the content at the beginning of the manga.

Also, there are "filler" arcs in the anime - original stories not present in the manga medium.

It is still mostly the same story, so you would like the manga if you enjoyed the anime.

Three animated movies based on Yu-Gi-Oh have been released at the time of writing, according to Wikipedia, with one more to be released in 2016.
There are no live action movies, though.
