No one has mentioned the cameos by the original Witch Mountain
kids: Kim Richards and Ike Eisenman. They played the waitress and sheriff who helped the main characters escape from the bar/diner. Ike (also Peter Preston in STII), looked just the same, only older. Kim has had a very hard life and is only now trying to get back into acting.
The current movie? Eh .. Although Dwayne Johnson is getting better with each film. Definitely a long way to go, but he's heading the right direction.
