is the movie shadow of a doubt 1995 based on a true story

The train starts up and, as it begins to speed, Uncle Charlie tries to throw his niece off the train.

Just before the train starts to leave, Ann and Roger disembark, but Uncle Charlie holds Charlie back. Roger, Ann, and Charlie board with him so that Ann and Roger can see his accommodations.

The next day at the train station, everyone from Santa Rosa wishes Uncle Charlie a goodbye and thanks him for the good that he has done for the city. When Uncle Charlie sees Charlie wearing the ring, he makes a toast and announces that he is going to be leaving tomorrow. Before the revelers come home, she searches Uncle Charlie's room and retrieves the ring. I don't regret having seen it, but there isn't exactly anything to recommend here.After the second attempt on Charlie's life, she decides to stay home from Uncle Charlie's speech and get ready for the party to follow. And the film is entertaining, albeit in an extremely lowbrow sort of way. It's hard to say if her performance is uneven, or it's just the character. So what's good about this film? Fairuza Balk is interesting. In effect, he invites everyone to overact as much as they care to. He lets everyone wink at the audience and make cute little sideways comments to the camera. In fact, he has next to no ability to rein in his actors. Speaking of Brian Dennehy (who I like very much as an actor), he is not a good director. Not that I have anything against the AA, but it just smacks of recent conversion fervor. At one point, his character references his time being sober as being virtually the exact same as Dennehy himself. The origin of this is embarrassingly close to the life of director/star Brian Dennehy. Then there's the shameless Alcoholics Anonymous propaganda. One of the lowest scenes is a retread of the old 'death as an aphrodisiac' cliché. Scene after scene is right out of the cheapest, lowest quality pulp fiction. The judge's lines are inappropriate and unrealistic. The script of 'Shadow of a Doubt' is bad.
