Say 3 sentences of what could have taken place in the past but didn't happen . Example:The film has disappointed me:

1) It could have been rained but there was no rain at all. The weather forecast changed dramatically and it was sunny weather. 

2) It could have been vehicle accident but luckily it didn\'t happened. The driver succeeded to turn to the left thereby everyone remained safe and sound.

3) My father could have become a movie star but unfortunately he didn\'t pass the interview with the producer of that movie.
