Characters that could be nailed by any other actor as well

Well there are some iconic characters played by certain actors/actresses that we think are irreplaceable because they lived those characters. But still if you think that those roles could be played by any other actor/actress of their contemporary, then who do you think could ace that with the same energy?

You can also discuss about the characters where you think that the actors were a pure miscast and someone else could have played the roles better.

Raj from DDLJ could have been played by Rajpal Yadav much better.

Kay Kay Menon could have totally nailed it in Irfan role in Maqbool

Every character that Ranbir played, any other actor could’ve played it better and with much better diction and with half the support he gets as a nepo baby starting with best of the directors to the best of music to the best of supporting cast etc.There is only so much acting one needs to do to rinse and repeat the same man child role anyway.
