Megan Fox has revealed that she did most of her own stunts in Transformers:

“I prefer to do as many stunts as possible. I’ll do as many as my insurance will allow me to do. On ‘Transformers’ I did about 40 per cent of my own stunts but on the next movie I did all of them. People are constantly shocked at the beatings I can take. It’s because once you have done ‘Transformers’ you feel like you can do anything. It’s easy after going through that.”
