At the time she had only done 'Shuga' so she really wouldn't have been on the 'international radar', and it's very doubtful the 'producers' of 'HOAYS' would have taken a gamble if they even knew of her. How many of 'us' actually watched 'Shuga' and how many Nigerians knew her name? Mr McQueen took a gamble... she wasn't a 'star' before then. It's just business.
Probably every coffee shop in LA has a star working there... most of them will never be found!

Yes I did remember you were in the Shuga thread and aware you knew. Every film will have people talking about alternative possibilities be it to do with the casting, story, plot or something. Great her first feature film has made her a household name but at the time of pre-production for HOAYS why would she have been thought about or considered?
Remember the NR Script thread? Not a soul mentioned her name; and that was well after 'Shuga'. It's no biggie, it's just how things are.
