I am going to tell you that people saying RDJ will always be their Iron Man is weird since no one else has played Iron Man yet. It is completely consistent with my original point.

The main "weird" thing about it is there is no prompting for it. There's no "Jamie Dornan to play Tony Stark" news article to even encourage people to say "RDJ you will always be Iron Man". Granted, The Flash has been cast in film form, but that film isn't out yet.

It's ALSO a weird thing to say because it is a very past tense sort of statement. It is a "There's a new Flash now, but you'll always be my Flash". Not only is there no "new" Flash, but he is STILL The Flash. He's the current Flash. Even when the movie is released, The Flash will still be in production making new episodes.

For these reasons (and probably more I haven't thought up yet), I find it a weird statement.
