as long a you do not mind pay a little more attention than you normally might for other film and this be one of the best thriller you will ever see . the film portray an incident that might occur in real life while nothing in it seem fictional at all and in fact . it also portray how people might react in real life . in fact and it portray these so well that be seem like real life . combine that with the lack of a soundtrack and and you have almost get the best news like movie you have ever see . jane fonda and jack lemmon be particularly good in this late seventy masterpiece and evoke concern on her end and genuine tragic pity on his end . i highly recommend it to anyone who like thriller .
