Anyone who has read X-Men knows Wolverine is the moody hot head with unbreakable bones, claws that pop out of his knuckles, healing factor and gravity defying hair. While the level headed leader who fires optic blasts that shatter mountains is Cyclops. Calm, cool and collected yet a babe magnet (Jean Grey, Psylocke, White Queen) and badass in his own right; Cyclops has never been given any cinematic credit. In X-Men he isn't phased by Logan's tantrums but doesn't have much to do besides be the punch line, have his girlfriend hit on and not be able to land a jet. In part II, he has a quick fight scene, gets captured, mind controlled and forgotten for much of the running time. His minutes quickly run out in X3 as Cyke is in brooding mode over the loss of Jean Grey and then seemingly vaporized by her returning spirit/ghost/whatever. Poor James Marsden...but seriously, he's doing alright.
In Seals, Biehn plays a leader who is strong yet compassionate and carries the responsibility of protecting his team while still managing to get the girl. Sheen plays hot dog Hawkins, the brash, "shoot first, ask questions never" type who tries to get the chick but fails. His recklessness ends up costing the life of a team member and gets him into a verbal beatdown with Curran, who is holding the stone of grief. By the end of the film Hawkins has to give up his selfish ways in order to save Curran's life and get the team to safety.
But X-Men was a gamble, big budget comic book movies were far from the norm in 2000; so much so that FOX hedged their bets around the mysterious loner/badass character, had drafts of the film titled Wolverine and the X-Men, shut down production midway to reassess and the fact that it was a hit and spawned 4 sequels is a bit of a movie miracle. Besides, Cyclops is already dead during the Days of Future Past story arc so we can't really complain about his absence.
Ah well, maybe someday, after Hugh Jackman stops playing Wolverine we'll get a decent onscreen adaption of Cyclops.
Here's the golf scene from Navy Seals featuring Biehn, Sheen, Bill Paxton, Dennis Haysbert and Rick Rossovich among others just cause:
