Evan Almighty, which opens tomorrow, will have a green message attached to it. I am not referring to the green message that most films carry with them in their hope to make money. Nor will the movie’s posters be colored green or have the Geico Gecko telling you to go see the movie. This green message involves the environment.

Universal Pictures, with some help from its sponsors, is spending roughly $25 million on its Get On Board eco-awareness campaign, with a website created in conjunction with The Conservation Fund. The campaign will give audiences tips on how to help stop global warming while advertising the film at the same time.

The educational site includes the Almighty Forest, where you can plant a virtual and a real tree for a mere $5 donation. A cool little extra is that contributors will have their name included on the film’s DVD.

[UPDATE: Watch the behind-the-scenes clip here after the jump where the director discusses the film’s environmentally friendly filming practices.]

The family comedy film has a plot with an environmental theme. In it, Evan (Steve Carell) is commanded by God (Morgan Freeman) to build an Ark, to be filled with a variety of animals. (Check out the behind-the-scenes with the animals clip here.) Lauren Graham stars as Evan’s wife.

Also, the movie was filmed in an environmentally friendly manner, something important to director Tom Shadyac. (Shadyac founded the bottled water company HtoO (Hope to Others), which donates 100% of the company’s profits after taxes to charity.) During filming, recyclable props were used and the cast and crew used bicycles instead of cars or buses on the set. [Source]

AMC, Regal, and Cinemark theaters are running in-theater spots on 13,000 screens showing how the film was made with the environment in mind. (A popular spot now is the one where they humorously go behind-the-scenes with the animal unit, interviewing crew members like “Assistant Production Assistant”!)

It’s nice to see big corporations taking on their share of the responsibility to help our delicate environment.
