Although not a name associated with big budgets and 3D special effects, Branagh said that he is relishing the release of the Hollywood blockbuster.
"This amount of interest in your film ahead of time, that's rare, that's thrilling," he said.
"Are you expecting it to please everyone? No. Are you expecting it to entertain everyone? Yes. And maybe they'll argue about everything they argue about anyway."
Australian actor Chris Hemsworth, who plays Thor, gave a ringing endorsement to his director's contribution to the film.
"I think what is so special about Ken taking on a film like this is you know the story and the character is taken care of," he said.
"Marvel is such a machine and the budget, the special effects and everything are going to be there.
"But he was also incredibly involved in that and his ideas of how to shoot through things and make the 3D work was hugely impressive."
Also starring Anthony Hopkins, Natalie Portman and Stellan Skarsgård, Thor opens in UK cinemas on April 29.
