Why would she say she was ignored after the Oscar nomination ?
Frankly, I don't understand why she would say she couldn't get work after her well-deserved Oscar nomination for the wonderful The Curious Case of Benjamin Button (2008) when in the following 5 years, she was in 5 No1 hit films - including two she headlined - all opening in the 23-56M range in the US : I Can Do Bad All By Myself (2009), The Karate Kid (2010), Think Like A Man (2012), Think Like a Man Too (2014), No Good Deed (2014). That's the kind of track record only very, VERY few Oscar nominees could pull off.
Also looking at her filmography pre-Oscar, all this proves that she was one of the rare nominees who actually managed to put that first nomination to good use and become a proper movie star in the process. If anything, she should be considered a great example and role model because she is not only an Oscar and Emmy nominated, Golden Globe winning actress, but also a bankable movie star and television legend-in-the-making.
All that would be an incredible accomplishment for anyone, let alone a 46 years-old actress of colour, considering the ageist, sexist, racist tendencies of the industry. My $0.02.
P.S. Not to mention she was also in a big hit with Tina Fey and Steve Carell (Date Night) and was cast alongside two of the most beloved movie stars of all time, as well (Larry Crowne).
