I first saw this film at the Dublin film festival in 1986 - and that remains the only time I've witnessed a standing ovation in a cinema.
Released in the same year as Crocodile Dundee, it looks a bit dated now, and to be honest, was never intended to be slick or fashionable. It's innocent, likable slapstick humour built around the oddball abilities of the title character, who is based on the director's (late) brother. A socially-disabled mechanical genius, Malcolm loses his job and so he reluctantly takes in a lodger. Initially dismissive of Malcolm, the lodger begins to recognise and appreciate his talents, and finally warms to him as the pair pull off a caricature of a bank robbery, and make an unlikely escape. Malcolm would undoubtedly receive a diagnosis of Asperger's syndrome today, and could be compared to Forrest Gump, albeit Malcolm is more mischievous and much less sentimental. The soundtrack, by the Penguin Cafe Orchestra, is also excellent and contributes much to the fun and energy of this film.
