A good movie with a bunch of kilts in it is Charge of the Light Brigade, from 1968, starring Sir John Gielgud and Trevor Howard. It isn't until the middle of the movie, when the British forces are landing at Calmita Bay that you see soldiers of the 42nd and 93rd Highlanders (no sign of the 79th that I could see), cavorting about in kilts. There is also a decent rendering of the Battle of the Heights of Alma, with the 42nd leading the charge up the hill, although it does show Major General Sir John Colin Campbell wearing the bonnet badge of the 93rd. Oh well, one can't have everything, I suppose!
