Forget the musicals.
I believe I've seen her in her only notable NY credits. She played Rosalind in "As You Like It" at the Public last season in a youthful and energetic (if a bit amateurish) production in which there were no real standouts acting-wise (I do certainly remember her and she was fine, but she was not distinguished in any way).
She also played the daughter in the dual Alan Ayckbourn comedies "House" and "Garden" two seasons ago at MTC. Again, she was just fine (the role didn't call for much more). Her British accent was a bit shaky as I recall, but she didn't embarass herself and handled the role's demands well.
She was a pretty and competent enough actress, fresh from acting school. She has talent, but then again, so do hundreds of others, and were she not Ron Howard's daughter now starring in the number one movie in the country (wonder how that happened), I doubt I'd be typing this right now.
