Given the title, you would expect 'Murder by Phone' to be a silly eighties slasher style flick...and that's actually more or less what it is. The most notable thing about this film is definitely the killer's modus operandi. Most slashers simply feature some guy with a knife, but the killer in this film has decided to go a step further than that and had developed a way to use an ordinary telephone as a murder weapon! Obviously, the whole thing comes off as being more than a little bit silly, but the way that the murders are carried out is amusing enough. The plot centres on these murders and takes the form of an investigative thriller, as our hero, Nat Bridger, begins looking into the death of one of his students. The film is never really all that interesting, but at least it's not boring and there's usually another murder scene just around the corner anyway; though unfortunately, they are pretty much the same. Director Michael Anderson does manage some fairly good moments of suspense, a couple of major characters have close calls (no pun intended) when speaking on the phone and there are various other bits and bobs to keep us interested. I can't say that this is a brilliant film, but it's at least worth a look.
