SURE!!

The Way West, starring Kirk Douglas. Douglas plays a wagon train master that leads settlers along the Oregon trail. They stop at Fort Hall manned by the British 4th Infantry Reg. and commanded by Captain Grant. Although the story line and main characters are fictional, Fort Hall and Cpt. Grant were very real. In the movie, the wagon train is met at the gate front by pipers in trews, if I remember correctly. But, later, I believe Cpt. Grant is wearing a kilt.

Across the Missouri features Alan Napier in a kilt. He dances a Highland fling with another Scotsman. The main actor is Clark Gable. No, Gable is not kilted.

Centennial, a TV mini-series from around 1978. Richard Chamberlain as Alexander McKeag, a scots fur-trader. I seem to recall one scene in which he wears the kilt. But, just one.
