The Rock has good crossover appeal, from action movies to children's adventure-commedies. Together, action fans + family-friendly crowd, is a pretty massive potential audience.

I think Cruise has the former but doesn't really do any of the latter, so his total potential audience may not be as large.

Rock is a great entertainer, cut his teeth in WWE. Why are we comparing? Is that even objectively possible?

Personally, I like the diversity he brings in all aspects.

One step closer to President Camacho!

Though given some of the other choices, not sure The Rock is that far down the list really..
