I've just seen this last theatrical cartoon directed by Bob Clampett, under the name Kilroy, on Thad's Animation Blog. It was made for the B-movie studio Republic and was a pilot of sorts for a new animated series there. It's a Grand Old Nag didn't do well enough for the movie company so Clampett's future would eventually be on television with Beany and Cecil in both puppet and animated form. Here, Charlie Horse dreams of movie star Hay-dy La Mare just as a director from Miracle Pictures ("If it's a good picture, it's a Miracle") picks him for his new film with the leading lady herself. Lots of very funny gags abound of Charlie's turns as a stuntman and his attempts at romancing Hay-dy. The print I saw turned black-and-white partly through but otherwise this was a very enjoyable short. Definitely well worth seeing for Clampett fans.
