Best part of the movie, IMO.
It's like he leapt out of a comic book. My only complaint is he is always in steel form even when he is inside the X-Mansion.
Yeah that was my only gripe with how they did Colossus really, we even see him eating breakfast in metal form at one point. So if they do have him in future movies they will need to cast a new actor for his human form.
In the comics, he was kind of stuck in metal form (he only changed with great difficulty) after the Marauder attack. I'm not saying that's necessarily the case, but this isn't unusual for the comics either.
Oh I know it happens, but they painted themselves into a bit of a corner if he is going to come back. They will need to cast another actor for his human form as they will have to show it at some point. This was just a little nitpick I had but overall loved him in the movie.
^ I think he was done a touch too broadly. Colossus is a bit more subtle than that (I also tend to think of him as younger). But he's far and way more accurate than any character besides Wolverine and maybe Magneto.
I agree that they painted themselves in a corner if they show him in human form, but I'm not sure why you're so certain they'd need to show him in human form at some point. They showed him eating breakfast in metal form, so I don't think they care as much as everyone else does.
The whole point is to exaggerate the elements of Colossus that make him unique. He's big, strong, and metal - let's make him consistently giant, strong, and metal. He's super nice and he's super good. He's super Russian. I loved the portrayal, but they didn't feel the need to do anything that distracts from that and his human form arguably distracted from it.
Well it was smart to keep him in metal form. This way they can cast any human actor but retain his metal form that makes him much larger.
Why we never see human form? Maybe he prefers it. It's not a weapon or a suit, it's who he is. He may transform into that while he sleeps. He can clearly eat food in that form.
I'm not sure why the praise. He was a bit of a caricature in this movie. Which works for this movie, but I don't think the Colossus that they presented in this film will work in a more serious X-men film.
