McG admits he did "a lot wrong" with 'Terminator Salvation'.

The director's reboot of the franchise - which starred Christian Bale - was widely criticised, and while the filmmaker insists he "did his best", he accepts why people were unhappy with the film but may eventually release an extended edition to show the parts he cut in the cinematic edit.

He said: "I feel like we did a lot right with 'Terminator', and I feel like we did a lot wrong. I really tried to deliver and do the best I could, with making that film. It worked for a lot of people. A lot of people didn't like The Ending. You live and learn.

"We did the best we could. I poured everything I had into that picture. Yeah, there's some outstanding footage out there, and we'll see if there's a director's release to come, in the future. You never know. Time will tell."

The 'Charlie's Angels: Full Throttle' filmmaker also admitted he would love to see the 'Terminator' franchise continue into the future.

He added in an interview with "I love the 'Terminator' franchise. I hope they make another one. We'll see where that takes us."
