He was in Hollywood one evening with a lady friend looking for a restaurant to have dinner in. They came to an Italian restaurant, but it was full. As the two walked away they heard footsteps behind them and it was James Dean, who had been eating in the restaurant and invited them to join him.
But first, Dean said he wanted to show them something. Parked in the courtyard was a little silver car that Dean had just bought. It was done up in cellophane with a bunch of roses on the hood. Guinness ask how fast does it go. Dean said about 150. Guinness asked, have you driven it yet, and Dean said no I haven't even been in it.
Then Guinness said that some strange thing came over him. In almost a different voice, Guinness said to Dean, "Please do not get into that car, it's now Thursday, because if you do, by next Thursday you'll be dead." They laughed about it, but on the next Thursday James Dean was killed driving that car
