did you watched mummy-4?

No, I haven't. Do you know what it's about? Is it going with the same series of movies starring Brendan Frasier? Actually, I don't remember a Mummy 3. I know they made (and I've watched all of these) The Mummy, The Mummy Returns, and then an off-shoot of the series called The Scorpion King (do some people count that as Mummy 3?). I haven't heard of them even planning on making a Mummy 4. When did/are they?
