Alex Pettyfer, the teenage actor that starred in Stormbreaker last summer is rumored to be up for a role in The Mummy 3. It's not known what role he would have if cast. If early reports are accurate, it probably won't be the son of Rachel Weisz and Brendan Fraser as he is set to have just returned from the army.... aged 22 (Pettyfer is 16). He certainly looks the part to play their son, maybe they will change the script and make him younger because really, what other role could this young kid have? Jet Li has already been cast, and it's expected Michelle Yeoh will have a role, along with Brendan Fraser and Rachel Weisz who are expected to return. As we have said before, the movie will be set in China. source - bloody disgusting, tv.com
