Othello casting

Othello: "My services which I have done the seigniory shall out-tongue his complaints"(19).
             "I am bound to thee forever"(127).
Actor for Othello: Will Smith. He's a really good actor and has done a lot of movies and i feel like he could portray Othello very well.
Iago: "Rouse him, make after him, poison his delight"(9).
         "And what's he then that says i play the villain"(101).
Actor for Iago: Will Ferrel. I believe Will Ferrel would be perfect for this role because he has experience in playing villains before.
Desdemona: "I have been talking to a suitor here, A man that languishes in your displeasure"(113).
                    "Sure, there's some wonder in this handkerchief. I am most unhappy i lost it"(155).
Actor for Desdemona: Angelina Jolie. She's a great actress and would really add to it.
Emilia: "What will you do with't, that you have been so earnest to have me filch it"(135).
           "I nothing but to please his fantasy"(133).
Actor for Emilia: Julia Roberts. She would be very good at showing the innocence of Emilia.
