Theatre of Death isn't a particularly bad film, but it's a disappointing one as it really could have been a lot better. The film plays out something like a British version of the popular Italian 'Giallo' subgenre, and features Christopher Lee as the head of a Parisian theatre. The film makes this theatre its central location, and it provides a good place for a macabre tale like this to take place. Two years earlier, Mario Bava showed how a colourful location could benefit a movie about various people being killed with Blood and Black Lace, and it would seem that director Samuel Gallu realised how this could be used as the theatre at the centre of the tale utilises a bright colour scheme, similar to the one in Blood and Black Lace. The theatre at the centre of the film specialises in horror productions, and this is taken to a new extreme when performers at the theatre begin turning up dead. We focus on a police inspector who is tied to the murders through his attraction to one of the performance artists, and he soon realises that there could be a link between the murders and the theatre.
For a plot like this to engage the audience, it needs both thrills and intrigue, and while this film has both; it doesn't utilise either to a satisfying degree, and this makes the resulting movie rather cold and difficult to engage with. The acting is above average for this sort of film, however, and lesser known members of the cast manage to stand out despite Christopher Lee's massive star profile. The film seems to have taken influence from the prolific Italians on the actress front, as Theatre of Death features some beautiful women, which bodes well with the grandiose central location. Christopher Lee doesn't deliver his best performance in this film, and really never breaks a sweat in the lead role, but it's always a pleasure to see him. The mystery is never too interesting, and the short running time never really does it justice. Full credit goes to the film for the ending, however, as the film comes good by the time of the climax, even though the mystery could have gone on a little longer, had it built up more tension. Overall, this is a decent enough movie; I wouldn't recommend going into it with high expectations, but Theatre of Death is worth seeing for fans of this sort of film.
