I've just finished watching August Rush (2007). Just a few minutes after witnessing again that jaw-dropping movie, I realized it was Keri Russell who played the role of Lyla Novacek. There she played the mother of a long lost child, August Rush/Evan Taylor. I did not fully recognize her maybe because of the over-whelming effect movie has. There, then, after, I googled her so I could be sure. I, eventually, confirmed that it was, after all, Keri Russell.
Keri Russell, a 32-year old woman currently married to a contrator, Shane Deary, started appearing on television the year 1991. She became famous after playing the role of Felicity Porter on a tv series, Felicity (1998-2002). Now, she has already appeared in 21 shows including movies. Her movies include: The Upside of Anger, Mission Impossible III, Waitress, and August Rush.source: www.imdb.com/name/nm0005392/
