On whether or not Tahir will appear as The Mandarin in any future sequel Tahir states:
"I don't know. My answer to that is that we created the character, not by accident, but by design, with a vague future. You can spin it many different ways and it should make sense, was the idea. One is this guy who has a connection to Mandarin at some point... or is this guy someone who might become Mandarin at some point? There's a case to be made -- and a pretty good one -- that two guys, who in the belly of a cave, almost like a womb, emerge out of that womb and one becomes Iron Man and one becomes Mandarin. There's a case to be made for that.
Tahir goes on to say-
"I think that's why they left the character open. If you remember the movie, [Raza] doesn't die. The same thing happened to Tony Stark: He gets paralyzed then comes back out of it.
If you're going to do a movie about Iron Man, you will have to, at some point, address Mandarin. We don't know when or how. They had asked me to be available for later times, if need be. So, we will see.
When asked if Tahir is in Iron Man 2:
"So far I don't think I'm in it. Things change very quickly. I know the direction that they're going in for the second one and to be very honest, it makes sense."
On the direction of Iron Man 2 Tahir states:
"They're going in a different direction, a different part of the world, a whole other challenge for Iron Man. If I do end up being in it, it will just to keep that story alive. If they do that."
