* FranchiseKiller / StillbornFranchise: As the ''X-Men Origins'' title indicates, this was originally supposed to be the first of many X-men films that dealt with the back story of certain characters, with the next movie after this one dealing with Magneto. Poor box-office and reviews killed those plans, leading to the semi-reboot XMenFirstClass Apparently many of the ideas from the unmade Magneto film were incorporated into ''First Class''.
* LongRunner: It marked HughJackman and PatrickStewart's fourth outings as Wolverine and Professor X, tying the then-record portraying a superhero held by [[Film/{{Superman}} Christopher Reeve]].
