…an old man with a walrus moustache [sic], dressed in a black suit or raincoat and with a trademark bowler hat. [T]he the bumbling old man would have adventures, partly slapstick, partly comic dance, with two young friends. Jon Pertwee also starred in the show in a variety of roles. The Mr. Pastry character had originated in the 1936 stage show Big Boy in which Hearne had appeared with Fred Emney.
Hearne first appeared on The Ed Sullivan Show in March 1954, with many subsequent visits. Buster Keaton was a fan. He was interviewed by producer Barry Letts for the role of Doctor Who when Pertwee departed but, wished to play The Doctor as Mr. Pastry. Letts, in turn, offered the role to Tom Baker.
I couldn’t find any clips for this movie but, I did find Hearne/Mr. Pastry on Ed Sullivan. ~Vic
