The Adventures Of Tintin writer revealed that plans for a sequel, a US remake and a spin-off TV series had all been discussed.
"We've had approaches for a remake and a sequel," he told Collider. "We've had approaches for a TV show to spin off it. But it's very early days, you know.
"So it's not out of the question but very early days, and I'd certainly like to do something different for my next thing if I get a chance to do a next thing."

Cornish added that he has already talked about a potential sequel with Attack The Block actor John Boyega, who plays street gang leader Moses.
"He has this image of a bigger alien attack on London, as if the attack we saw in Attack The Block was just the [first] wave and there's another wave of bigger creatures," Cornish explained.
"He described to me this image of Moses leading a whole army of hood kids across the Thames, next to the houses of Parliament. So yeah it's really fun to think of stuff like that and what we could do."
