Thor went on to become the hero of his own film (Thor (2011)), and was then re-teamed with The Incredible Hulk as a member of The Avengers (2012). Lou Ferrigno would voice the Hulk in the latter film as well.
This film presents Dr. Donald Blake and Thor as two separate characters. In the comics Thor is in fact Blake's alter ego, which he transforms into by means of the hammer.
In the fight on the beach when Thor and Hulk fight the goons from the copter, the green make-up on the Hulk's face is noticeably lighter than that used on his body.
When the thugs attack Banner at the lab right before the 2nd hulk out Mike screams at Roy the Banner grabs Mike's arm causing him to shoot one of his thugs in the chest but within a few seconds you see the thug who was shot uninjured.
When Blake revels himself to David at first he said he meet him ten years ago as the guest genius and that David had a beard but 10 years prior to the events here David had no beard and he was already the Hulk.
