Jeremy Renner loved having the opportunity to play with ''Thor's hammer'' on the set of 'The Avengers'.
The actor - who plays Hawkeye in the Marvel Comics movie - loved getting to spend the day with all of the other stars of the film, although admits it was like ''Halloween'' with everyone in costume.
He said: ''When everybody was together. That's the most memorable and creepy and funny. Getting to play with Thor's hammer while he stroked my bow. That's going to get me in trouble! It was getting all the actors in one room, all in costume.
''It was like Halloween. They were hesitant as humans, but then they were dressed up like silly people. It was great to laugh at each other. That will always stick in my mind.''
Tom Hiddleston, who plays villainous Loki in the movie, admits the scenes with all of the other characters - which includes The Hulk (Mark Ruffalo), Iron Man (Robert Downey Jr.) and Captain America (Chris Evans) - were his favourite too.
He added: ''It was the whole summer, for all of us. We had so many different experiences together. It was an amazing time for me to work with some of the greatest actors in the world.''
