Dentist on the Job

From Freepedia

Dentist on the Job was a 1961 British comedy film, in black and white, directed by C.M. Pennington-Richards. It was released in the USA with the title Get on with it!. The film was co-written by Bob Monkhouse (who also appeared in the film) and Hazel Adair. Notable actors appearing in the film include Kenneth Connor, Shirley Eaton, Richard Wattis, Charles Hawtrey and Arthur Mullard (uncredited).

The film is referenced in the Special Edition DVD of Monty Python and the Holy Grail, since it is the film which is erroneously shown by the projectionist (Terry Jones) at the beginning of the film (probably leading many DVD buyers to assume that the DVD contained the wrong film altogether). This film was presumably chosen for its alternate title, Get on with it!, a phrase used throughout the Holy Grail.
