See, I didn't mind Jones in the role nor how the character was portrayed in the film. I love the character from the books, but when you translate him to film its tricky how you go about it.
I didn't mind his lines and delivery that made it into the film per se, but they definitely limited themselves to what could be done with the character when they cast Vinnie Jones. If they had cast a good character actor, someone who can actually act, then we probabloy would've got a more interesting charcter.
As i said, they had him goading Wolverine with some more dialogue outside Jean Grey's house, but the delivery was so bad, they cut the lines. I assume it was the delivery and acting, because they were delivered far less successfully than his one-liners.
So, going by that, if they had wanted to give the character a bit more to go on, rather than just one liners, then they would have been hamstrung by that casting.
See, over in the UK Vinnie Jones had a rep as a sportsman when he played football(US translation: soccer, haha), and that was along the lines of Juggernaught, he would plough right through folk, (Jonathan Ross once described him as a 'human scud missile'*)so i guess Vaughnn thought it would be funny, and apt, to cast him in that role, but he can't act, so it was a bad casting imo.
*this piece of footage can actually be seen on a Nirvana live compilation, as Ross says it right before he introcuces Nirvana performing 'territorial pissings' on his show, just pointing this out for the fun of it.
For starters, back in '05 when X3 was in production, we didn't have this kind of CG perfected yet.
Now you can do a CG Juggernaut & have him look enormous yet real.
eh, I'd say the CG in Ang Hulk was on a par with what we have seen in the Avengers trailers, if an X3 had been made with proper preparation time, they could've done a CG enhanced Juggernaught, as you are suggesting below.
As far as the performance goes, because there was really no time to address the connection between Marko and Xavier in X3, Jones' dialogue basically consisted of quick one-liners that I thought he delivered well.
I also think it was smart to make Marko British since he grew up with Xavier & Xavier grew up in the UK.
But Jones wouldn't have been capable of that kind of performance, if they had went that way.
Because the characters are now 30 years younger than they were in the OT, you can do a Captain America effect with The Juggernaut. You introduce Xavier's step-brother Cain as a young soldier who is maybe fighting in 'Nam when he comes across the cave & the ruby. So you only use the real actor for a bit until the transformation occurs. Then you go CG & hide his face under the helmet. Later on, you lose the helmet during a fight with the X-Men and do your best CG/Real match-up.
In summary, Ratner did the best he could with The Juggernaut in '05, now there's tons of room for improvement as showcased in the photo above.
I myself would love to see a Hulk-sized Juggernaut under the control of Fassbender's Magneto fighting Xavier's Second class.
Aye, it would be good to see a CG enhanced Juggernaught at some point, I don't know about doing all the back story from the books though. I think they should just keep him as a mutant, and forego the Xavier connection, if they come up with an interesting plotline where that serves the story and doesn't come across as wonky, sure, of course, but it could get over-complicated. You have to forget about any continuity to X3 if they go with the Xavier family connection.
