Donner told Entertainment Weekly:
“I love what Jen Lawrence has done with [Mystique], and I feel like because she is in such a crowded ensemble, there’s so much more opportunity if you were to follow her solo.”
In fact, Donner envisions a number of solo X-Men titles:
“There was a regime [at the studio] that didn’t see the worth in [spin-offs], and the current people who run Fox understand, embrace it, and we’re going to do right by it. I’d like to do Gambit. I’d like to do Deadpool. We’ll see. There’s a lot of really great characters.”
A solo Mystique movie would be great, but only if they let her be bad — and I don’t really see that happening. Blue-skinned mutants must be proper role models, doncha know…
Personally, I’ve never really liked Gambit in the comics — not his power, not his costume, not his staff, not his patois and not his personality. And on film — in X-Men: Origins — Wolverine — he came across as even shallower. And don’t get me started about Deadpool, a joke character that ended up taking on a life of its own.
