My friends don't agree....?

In X-Men Evolution, Wolverine was in the war with Captain America. Then he visited Captain America when he was frozen at a S.H.I.E.L.D. base. %26amp; in Iron Man, Samuel L Jackson played Nick Fury, which is SHIELD. %26amp; in X-Men Evolution, HYDRA created Wolverine (Weapon X to them) %26amp; X23.... SO MANY QUESTIONS! plz answer! ITS ALL CONNECTED ISNT IT?????My friends don't agree....?
Wolverine was born a mutant. the Weapon-X program just infused him with Adamantium. I'm not sure the Weapon X program was created by Hydra. The Super-Soldier project was theirs initially but I could be wrong, but I thought It was created by Shield to counteract Hydra.My friends don't agree....?
well they are all based on DC comics and yes there is a lot of overlapping. Nick Fury is seen in "Iron Man" and they both iron man and Nick Fury are talking in the Hulk movie. then at the end of the Thor movie you hear about S.H.I.E.L.D and after the credit you see Nick Fury talking to someone about the portal and Thor and the power he has. It would not supprise me that this was all planned because they have prob. known that one day they are going to do the Avengers (which incorparates all these characters in the group called the Avengers) as a movie which has Iron Man, Thor, Nick Fury, Captain America. and so forth.
