Michael Bay almost cancelled Transformers: Revenge of the Fallen when Shia LaBeouf was injured, femalefirst.co.uk reports.

The director says production managers considered scrapping the action film when the lead actor injured his hand in a car accident midway through filming and admits they were “lucky” to complete it.

He said: “I actually read it on CNN online and was like, ‘This can’t be true.’ I called my line producer, Ian Bryce, and he said, ‘It’s true,’ and I was like, ‘Oh, my God.’ He said, ‘Let’s shut down,’ and I said, ‘We can’t shut down!’

“We were very lucky because we had shot a lot of the beginning of the movie and we were right at a turning point.”

LaBeouf recently revealed he will never regain full use of his hand following the crash in July last year.
