20th Century Fox wants Rupert Wyatt and Matthew Vaughn to return for the Rise of the Planet of the Apes and X-Men: First Class follow-ups.
Tom Rothman, Fox's chairman and CEO of filmed entertainment, has said that the company is trying to get the two directors back for their respective sequels.
"Both of them were really great scripts and so we have to be sure to get great scripts again," he told ComingSoon.net.
"We're working hard on the scripts for both of them, but we have every hope of moving forward with them."
X-Men director Vaughn is currently on board to film adaptations of Mark Millar's Superior and Secret Service comics.
Rothman was speaking following his reception of a special tribute at the Gotham Independent Film Awards.
