Dwayne Johnson makes his film debut in “The Mummy Returns” (2001). He yells a few times and then leaves, only to return as an early CGI attempt at a man-scorpion that looks more like a Rockaroach (See what I did there?). That’s how history is going to remember this workmanlike sequel to star Brandan Fraser’s 1999 attempt to exhume Indiana Jones. Not bad as far as summer popcorn movies go. The treasure-hunter story picks back up rather seamlessly and there’s a decent mix of new characters to go with returnees to keep things relatively interesting. It’s just not as fun.
