Stephen Amell and Robbie Amell are fans of science fiction. Not only do they work on the CW’s “Arrow” and “The Flash,” respectively, but they also want to spend their summer on the set of a sci-fi movie. However, they need a little help to make that happen. The cousins launched an Indigogo campaign to make their movie, “Code 8,” a reality.

“Code 8” is a film set in a world where police are targeting people with superhuman abilities. When the teaser trailer was released, not much information was available, but the clip promised to give fans more information on March 22. On Tuesday, a 10-minute short film for “Code 8” was released. Along with the video comes a link to Indiegogo.

The Amells want to make this a full-length movie, but they need some financial help. The campaign will last a month, and over that time, they hope to raise at least $200,000. They received over $35,000 in the first three hours. While that goal seems like a very small budget, Robbie clarified that they don’t want fans to finance the entire thing.

“We’re not really ready to say how much that we want. … We’ve set our goal on Indiegogo at $200,000 because we don’t want to feel like the fans are really more just helping us get it off the ground,” he told Coming Soon. “I don’t think it would be fair to ask everybody for money. We’re putting our own money into it. If we’re not willing to take a chance on ourselves, then why should we expect anybody else to? But the nice thing is, because of people like [cast member] Sung Kang and because it’s a genre movie, we can presell territories. There’s a lot of ways to get this off the ground.”

Watch the short version of “Code 8” below:

The movie would allow the actor, who plays Ronnie Raymond/Firestorm on “The Flash,” to work with his cousin, who plays Oliver Queen/The Green Arrow on “Arrow.” Though the two were in a crossover event together, they didn’t actually share much screen time.

“Stephen and I always wanted to work together,” Robbie said in a video on the fundraising page. “We got a taste of it on ‘Arrow’ and ‘Flash.’ We wanted to do something bigger together and actually talk to each other on camera.”

Though they won’t release many details about the movie, they did tease that the cast will expand. “I’ll be in it, so there’s that. Sorry, spoiler alert,” Stephen added in the video. “I couldn’t be in the short because of the whole ‘Arrow’/ ‘Teenage Mutant Ninja Turtles’/ dueling vigilantes bongo that I’ve been playing for the past 18 months.”

If simply seeing the CW stars work together isn’t enough of an incentive, the filmmaking team is also offering perks for those who help fund the movie. The rewards start at $5 with just a name on their website, but the tiers go all the way to $50,000 which will make the contributor an executive producer on the film. Other perks in between include comics signed by “The Flash” cast and script pages from “The X-Files” signed by David Duchovny, Gillian Anderson and Robbie.
