Have Amon Amarth and Judas Priest guest star in the Rampage movie

With New Line Cinemas making a movie based on the Rampage game series, I thought things would be interesting if the movie had guest appearances by the bands Amon Amarth and Judas Priest. Now I know what you must be thing, "but metal ruins the suspense", but the bands themselves will be appearing in the movie. Songs from them will be performed by them in the movie itself, Amon Amarth's "At Dawn's First Light" and Judas Priest's "The Sentinel". Not only will this increase ticket sales, but young Rampage fans will know the joys of metal.
