The first Stooges short to feature regular support Philip Van Zandt, after having a bit part as a soldier on "Boobs in Arms" (1940).
The castle set for this short was originally built for "The Bandit of Sherwood Forest (1946)", and was also reused for "The Hot Scots (1948)" and "Fiddlers Three (1948)".
There's a recurring theme in chase scenes in this short and others. When the Stooges are escaping from their enemies, there is a hallway with several doors on each side. They go in and out of the doors with their pursuers chasing them. The camera is stationary, with occasional film stops so that right after they go in one door, they are seen coming out another one down the hall.
Columbia production number 4082.
