They got Tyler Mane back as Sabertooth.
Vinnie Jones didn't want to return. He refused to wear that muscle suit again.
From a pure collector standpoint, some of these characters, even ones who were in minor roles, are all opportunities to be Hot Toys or Marvel Legends figures.
Would Vinnie Jones as Juggernaut be made by Hot Toys? Unclear. But if he had returned, a Marvel Legends set would be a stone cold lock. Even just a quick pan of the original X Men under Singer in the TVA old grainy footage on screen, that could have justified a ton of Marvel Legends releases.
If Blade had gotten a 3 second quick cut added where he's choosing weapons out of armory, just touching them justifies making them and putting them into a figure set. That was my fantasy scene for John Wick. He has 10 weapons on a table, that we've never seen before in our hobby, not even the military side of it, and he only has 1 bullet, round or shell in each one, and he has to use each one in a quick 3-4 minute scene. Now justified to add into the Hot Toys or a knockoff release.
There's always a more optimal way for us as collectors to get more toy options, nostalgia options and better gear/accessories. But sometimes it just doesn't work out.
A lot of the times, I just hope any IP, when decisions are made, they are made by people who have at least some sideways glance at the potential merchandising. And have a good eye for cool stuff. Like Wakanda Forever. There was so much potential for some pretty neat designs and weapons. Even if the film wasn't so great. But alas, more fodder that will sit at Ollies for the next 5 years or so.
When I was a kid, EVERY KID wanted an AT AT from the Hoth Battle in ESB. Every last damn one of them. I wish that was the litmus test of the aesthetics and designs all of the time. Would someone jump out of their seat, point at it, and say, "I want to buy something like that, right now, and I don't give a damn what it costs me" But that's just me, I just want more cool toys.
