MR. TOPAZE

 The only film that Peter Sellers ever directed was this comedy set in the Paris of the not-too-distant past and based on a Marcel Pagnol play that was filmed several times before, though this version, produced and written by Pierre Rouve, is chock full of well-known English character actors pretending they're French. In hindsight, it might feel like a strange choice for Sellers' directorial debut, and sole effort, but at least he's got the plum title role of "Mr. Topaze". a mild-mannered and scrupulously honest school master who loses his job because he won't give a rich man's son a better grade. As it happens, said rich man, (Herbert Lom), is also a crook who then employs Sellers to act as a 'front man' for his crooked business. 

It's shot in Cinemascope which doesn't really suit the material but on the plus side those character actors do throw themselves into the very old-fashioned material but it's certainly never as funny as it thinks it is. Sellers reputedly hated it, so much so that he tried to have all the prints bought up. It's not a bad film as such and at best it might be described as a curiosity and so out of step with other comedies of its time, it is, at least,  of more than passing interest but ultimately it's that supporting cast, (Leo McKern, Lom, Michael Gough, Martita Hunt, John Neville and a surprisingly good Nadia Gray), that saves it. It might have been better with a different director, (Sellers was clearly not up to the job). I suppose you could call it a cult movie and now that it's resurfaced maybe you should seek it out.
