Blooper

The young ladies referred to in the title are in an all female institution, hence are technically not "co-eds".

In the last cliff top scenes, the Falcon is walking along the cliff top, but the background scenery does not move showing him to be walking on a treadmill.

Towards the end of the film, The Falcon and Vicky Gaines are walking along the studio cliff top path (with back projection scenery), discussing Dr. Graelich's marriage to gain access to the U.S. The next shot has him following them on the actual uphill and uneven cliff top path, with his hair disheveled from the breeze. However, when he then joins them, his hair is neatly combed and he answers the question concerning his marriage, notwithstanding he could not possibly have heard their discussion as he was some yards away on the cliff path at the time.
