@norrinboltagonprime21: Don't get me wrong I love the ultimate universe (pre-Ultimatum) and totally agree with you that the directors should be allowed to tailor the characters to fit the film they envision, I'm just wondering if besides the inclusion of ultimate elements into the characters of the MCU, the the inclusion of ultimate mentality on capital punishment is needlessly muddying the characters up to a wider audience with no experience with the 616 characters. I may totally be jumping the gun since my feelings are based mainly on Iron Mans actions in IM3. Not to drop any spoilers but he does kill maybe a dozen people in and out of the armor in IM3 with no moral questions. In my personal experience the people I've talked to who have never read comics seem to get the impression from the films that the Marvels have the authority to kill when they deem appropriate like a police officer or soldier and are more than willing to do so than "pussies like Batman and Superman" (quote from a dude in the theater.) The marvels are unlicensed, self appointed protectors and so have NO authority to kill outside self defense which legally allows only as much violence as reasonably necessary to end the attack anything more= battery or manslaughter. In comics they generally avoid killing at all costs and do so usually only to prevent immediate deaths of innocents. As for the films themselves,while the storylines and costumes are more 616 there are many elements of Ultimates tossed in and the characterizations themselves owe a LOT to the Ultimates characters and general darker mentality.
IM123- for as many women he's dated before the Ultimates, Stark was never really seen as a partying/womanizer in the 616. Most of his girls were long term committed relationships and his drinking was sulking alone in demon in a bottle trying to forget his problems not party. Ultimate stark said he dated a diff girl each night/ drank while partying/ and was a shameless attention hound. Since the success of ultimates the 616 has adopted several of these traits but he's still a pretty serious dude in the 616(director of SHIELD, Civil War, Extremis...etc). I consider the IM1 created Stark personality that has carried through all the films more an adaptation of Ultimate Stark with a little 616 somber stark mixed in. IM2 played up more the 616 serious Stark but the fun Ultimate Stark was still on display. IM3 plays up the 616 unsure stark trying to live up to/control the crazy world that exists since Avengers while doing it with the Ultimate Starks personality and morality of life.
cap- here I'd say is a definite ultimate cap vibe. For all the man out of time idea behind cap since his revival in avengers to the release of ultimates he never really seemed out of time. His ideas were pretty progressive and too appropriate for the 70s/80s/90s for a dude from the 40s. His feelings on killing in or out of war, relationships, the government, liberal rights all seemed out of touch with the 40s but perfect for the era the stories were written. But in Ultimates this was a guy with a mentality of guy raised in the 30s/40s so out of touch with thoughts of people his age from today. Being that he was a soldier in the worst war ever seen to that point he was willing to kill. In first avenger and Avengers cap seems like a guy with a 40's mentality on things/ a soldier who killed in battle and used firearms when appropriate seemingly having much more inline with Ultimate cap. Still his big soft heart and dreamy view on America is what made 616 the symbol of hope that ultimate cap never seemed is showcased prominently.
avengers- I'd say while the look and story are definitely 616 inspired but the set up is strongly ultimate based. First the whole avengers initiative being shield run and created is obviously ultimate. Fury's position on the team, interactions with them and manipulation of them is also key to the ultimates. Also the dysfunctional nature of the team that was key to the story was the point of Ultimates vol 1 and rarely an issue in 616 pre-ultimates. As you said hawkeye seemed to step out of the pages of Ultimates with his costume/personality/and morality.
By the way guys thanks for the responses I appreciate the notice :)
