This is strange. They're rebooting a franchise that was itself a re-imagining of a classic horror film from decades ago. I actually think Stephen Sommers original The Mummy is a really entertaining film, with good pacing and great comic relief. The original Karloff film is interesting from a historical perspective, and I do enjoy the classic Universal horror films, but it doesn't hold up today as being very scary.
I agree with ilovemovies that Wiseman's attachment seems to indicate that they're going for more of an action approach similar to the Stephen Sommers, but I seriously doubt it will be as fun as the Brendan Frasier film. I just don't have much respect for Wiseman as a filmmaker.
