Wryn wanted to pursue acting because both of her siblings have appeared in acting roles. Her first role was in the 2004 film, Hulk as a younger version of Jennifer Connelly's character Betty Ross. In 2005 she appeared in an episode of The King of Queens. Her first leading role was in The Last Mimzy, which was released on March 23, 2007. Wryn could not yet read during filming of The Last Mimzy, and thus the script had to be read to her so she could memorize it.
