An OOO movie could happen. OOO: Anhk ReBirth

....Curse you and your reasonable questions. :lol

You know what kinda Rider movie I'd like to see? Kotaro Nogami, Masao Kurenai and Eiji Tomari getting together and having a big old Kamen Riders of the Future adventure. With Ryotaro, Wataru and Shinnosuke sympathising with each other over how weird it is to have your future decendents running around in the present and/or theorising on their possible mothers/grandmothers.

Throw in Aqua and I'd be down for that.

If they reveal that at some point Taiga resurrected Mio and then she and Wataru fell in love again and eventually "constructed a violin," I would be very happy.

Poor Mio, getting axed by a butterfly. :(

Nah, they should have a movie where Rider actors are being chased by kaijins in comedic fashion. And take hints from This Is The End and Tropic Thunder.

To be honest, I always thought she deserved it. Asking Wataru to kill Taiga, his own BROTHER and someone he really valued as a childhood friend too, was really horrible of her and I could never forgive her for that. I already disliked her before, but that was just awful of her.

That's be weird, but awesome! But I imagine they couldn't fully commit to actresses being the moms since they can hardly get previous main riders back anyways, let alone people for supporting roles.

Really depends on the actor though. While Takeru Satoh and Kouji Seto would probably not reprise their roles in the near future because they're way too busy, Ryoma Takeuchi already stated that he'd love to be back as Drive in the future.
As for Dori Sakurada, Kouhei Takeda and Mackenyu, I really think it depends on their schedule. Sakurada and Takeda reprised their roles before, so it might be possible.

Which Kamen Rider show besides Amazon do you think has the most violent and brutal moments? I say Kuuga and Agito got pretty bloody at certain points.
