Visible crew/equipment: When Mel Gibson is getting his red boat ready to put in the water, his friend comes out of his house to talk to him. You can see the camera crew reflected in his friend's sunglasses.
Visible crew/equipment: In the scene where Randall is chasing the big blue, he trips and if you look closely in the background, a camera is perfectly visible..
Continuity mistake: The actress loads her 35mm Praktica camera with Kodak film. That's not really strange, but the film is situated in 1968 around the invasion of the Russians in Prague. The film cassette is clearly visible as having DX coding on one side for setting the film speed automatically. This feature had yet to be invented in 1968, because it was released in the early 80's.
Continuity mistake: When Darcy throws her bridal bouquet, the direction is to the left of the church, yet in the next shot, a girl at the top of the church steps is waving it in the air.
Revealing mistake: The "Great Train Robbery" actually took place on a two-track railway near Cheddington - the West Coast Main Line. However, the filming took place on the Great Central Railway steam line near Loughborough, which only had one track at that time. They laid a second track for the filming, but omitted to cut down a large tree at the end of the rails, which would block the path of a train. This is blindingly obvious, especially as they show this "atmosphere shot" twice. The tree is still there the second time.
Visible crew/equipment: When a very powerful gust of wind blows Jack out of the castle, a support wire can be seen attached to him.
Other mistake: When Danny fled from the FBI cars and went to his house to get Harry, the back door was ajar and the dog (Jomo?) was near the steps. There apparently was a dog/pet door near the bottom of the door, leaving no reason for the door to be ajar in the generally hot Florida temperatures. Right before the dog goes into the house with Danny's shoe, there is a flash of a hand that quickly went behind the door, but someone was there. (00:04:37)
Plot hole: At Tim's funeral, Olivia's attorney tells her that Tim had himself removed from Olivia's Last Will and Testament, proving he loved her and didn't want her money. However, an attorney could not legally change a client's Will without that person's knowledge and drafting a revised version.
Suggested correction: Not true. Anyone can have themselves removed as a beneficiary of a will. This is done by signing an Affidavit of Disclaimer of Inheritance at such time as someone becomes aware that they have been included in a will as a beneficiary. This is what Tim meant when he said he had removed himself from Olivia's will.
