Making Gears Of War Trailer (Live Action Movie)

[lollycop]

Guys, i'm making a Gears of War live action trailer (of course the lokus will be animated/CGI) and already got the whole trailer planed out. It starts out with the song Strawberry fields and shows clips of landscapes and mountins and citys all peaceful, then all of sudden everything goes black and you see buildings blow up and at the very end you see a beserker charge a bus and the flys into the screen to make it black. Then says Gears of War. But I need a clip of the beserker, is there a movie or a animated gif thats very similair? If so, or if you have any hints, please post.
