Ventriloquist "Corky" is about to hit the big time when he starts to realize fame and fortune isn't all it's cracked up to be. He retreats to a lakeside cabin owned by the woman he fell in love with as a teenager but things turn nasty. He is suffering from schizophrenia and uses the dummy to voice the things he can't bring himself to say. This is done superbly and Anthony Hopkins plays it all extremely convincingly. Ann-Margret puts in a mostly believable performance too although at times she seems a little unlikely. It doesn't detract though, her screen presence adds a lot to the movie and she looks radiant as ever. For a while when watching this film I had a horrible feeling that the dummy would turn out to have an intelligence of its own and would start walking around with a knife in its little wooden hands. Thankfully this doesn't happen and it's a much more sinister and impressive film for it. Overall this was surprisingly watchable, well made and at times genuinely scary. The violence is filmed well and doesn't resort to bloodfests to get the message across. One of the few 70's horror flicks I've seen with good acting and a credible plot, well worth watching!
