Reynolds relied on his imagination and his director when it came to the stunning visuals in "Green Lantern."
In Hollywood's latest superhero movie, Reynolds plays a test pilot chosen to be a member of an intergalactic squadron working to keep peace within the universe. He's given a mystical ring that bestows him and other green lanterns with otherworldly powers.
The film uses Hollywood special-effects magic to create out-of-this-world visuals, but for Reynolds, he is forced to act without really knowing what will be around him on the big screen.
"You just have to have a lot of faith in these amazing artists and these guys that are nothing short of magicians behind the scenes who are creating this world for you," Reynolds said.
While "Green Lantern" has its share of action and drama, along the way, it also relies on humor.
"This isn't 'The Dark Knight.' This is a film that is meant to be slightly aware of itself," Reynolds said.
The movie is being marketed like mad, with "Green Lantern" products of all kinds.
Reynolds said his favorite piece of the marking is the pajamas, "because we all need a good onesie."
The movie hits the big screen on Friday.
