I remember asking myself this question back in 1990!
aint that crazy?
Anyhow here's a rough draft of a cast I thought of back then and a few I think would have done good now back then.Sorry if some of these pics seem cheesy but it's what I thought.
Cyclops: Dolph Lundren (Spell check!)
The guy played He-Man and killed Apollo Creed in a Rocky movie.He also starred in the very forgetable,yet awesome Showdown In Little Tokyo.He also played another Marvel superhero in the Punisher.He has that dry objectivism (is that even a word?LOL),that is embedded in the character of cylcops.Especialy during the early 1990s.Take this pic of him and slap the Visors on.He looks a lot like Cyke.
Jean Grey: Cindy Crawford.
Yep that's right the model Cindy Crawford as jean Greay.She had the red hair and the look of Jean.I think her first attempt at acting failed.I think Cathy Ireland might have pulled it off too.

For Wolverine I would have gone to none other than Glen Danzig.He's only 5 foot 4.(Maybe 5 FT 6) and was buff.Brian Singer even approached Danzig about playing the part,but Glen turned down the part due to his touring and apparently he didn't like the script.

For Colussus I would have went with Arnold Swarchenagger or however the hell you spell his last name.He had the face and the body to pull off the Russian X man.
Proff X.None other than Patrick Stewart.Would have done great back then too.
I find some more here in a little bit.
