[TOMT] looking for an old movie with little people

Looking for an old movie. It's with a bunch of Tom thumb sized people and regular size people.

In the end, the main little guy has to choose his bride, and he has one in mind. However he is told that the bride chooses the husband. So it's a race to catch him and whoever catches him becomes his bride.

In the end, the girl he wanted is the who catches him.

It's in old technicolor, like the old robin hood movies with Eroll Flynn.

Thank you.
