Fess Parker (Davy Crockett) and Jeff York (Mike Fink) would appear the following year in Disney's "Old Yeller", but don't have a scene together in that movie.
The movie was made from two episodes of Disney's TV show spliced together and released as a profitable feature film. Walt Disney filmed his show in color even though few color TVs were being sold as yet. As a result, the Davy Crockett episodes could be turned into instant movies by stitching the episodes together.
Jeff York would appear with Fess Parker again in the TV series "Daniel Boone" ('Grizzly') in 1966.
Pecos Bill in "Tall Tale" (also from Disney) says, almost word for word, what Captain Fink says when he introduces himself to Davy.
Supporting actor Kenneth Tobey gained fame in the role of the heroic Air Force captain battling the alien in "The Thing from Another World". His red hair kept him from lead roles in color films.
