I heard that Adriana Fonseca, Mariana Seoane and Ana Layevska are going to audition for B.D.O. next week. Of those I'd choose Adriana Fonseca but still, I don't think of the other 2 as protagonistas.
I remember that for the infantil "Vivan Los Niños" they auditioned a lot of actresses for the maestra too. Some good ones and they ended up choosing Andrea Legarreta. I remember that Gaby Spanic, Angelica Rivera, Angelica Vale, Paty Navidad and lots of others had gone. At the time they chose her I didn't think much of Legarreta but I now think that she is doing a fine job.
We'll see how this B.D.O. turns out.
Keep in touch.
