10 More Actors Who Took Method Acting Way Too Far

Sylvester Stallone's dedication to his character Rocky Balboa showed that the actor was willing to put his body on the line to portray the iconic boxer.

And that's exactly what he did.

Stallone pushed his body to the limit, undergoing an intense training programme so as to portray Rocky as a powerful force.

He wanted the fight scenes in Rocky IV to be as realistic as possible, telling co-star Dolph Lundgren, who played Ivan Drago, to punch him in the scenes they filmed together.

During one take, Stallone received a heavy blow from Lundgren, causing the actor to spend nine days in the ICU with a severe chest injury and delaying filming for two weeks.

However, the actor didn't immediately go to the hospital when he received the blow. Stallone insisted they continue filming, with the crew not knowing how badly Stallone was injured.

It was only when his condition worsened after shooting finished for the day that he was rushed to the ICU.
