Once You Kiss a Stranger...

A pointless ,useless "remake":although he modified Highsmith's novel,-he told it so in the foreword he wrote for the novel-Hitchcock kept the essential and produced a classic thriller you can watch again and again,with lots of memorable scenes (the murder seen on the glasses,the keys,the merry-go-round which goes crazy,and more).Plus a first-class performance by Robert Walker.

"Once you kiss a stranger" keeps the last word,but there's no more train ,the action takes place in the world of golf;why not after all? But by doing so ,without any suspense ,with a dreadful cast (Carol Lynley as a woman-child is so weird we do not know if she seriously plays or she's having fun with a stupid part of a girl who wants to get rid of her shrink -if you kill my shrink,I will do away with the top golf champion,and you will be number one!-,the director produced one of the worst thrillers of all time.

It's to state the obvious to write that you'd better choose "strangers on the train" (1951).As for Lynley ,take "Bunny Lake is missing" instead.
