My friends saw the twist coming because of the casting choice.

I showed the movie to a couple of friends, and they both saw the twist coming and they said it was because the actor who played Dil looks like a man in the wig, and they could tell.

I already knew of the twist, because it's been given away so many times.

So my friends said they saw the twist coming cause they could tell the actor was a man. That got thinking. What if instead of getting a male to play the role, they got a woman, and put fake male genitalia on her, or used a male body double just for the below the waist shot?

It seems to me that that would have done a better job at hiding the twist, and others may not have seen it coming then, cause the character would actually be played by a woman which would hide it better?

What do you think?
