If you know The Avengers pretty well, you might recognise Ashley Johnson from her minor role as Beth the waitress in that movie - she's the one who praises Captain America on TV in the aftermath of the Chitauri invasion. She originally had a bigger role, meeting Steve Rogers in a scene intended for early on in the film (which also boasted an awesome Stan Lee cameo), but it was cut from the released version. Whedon fans will also know Johnson from her other two supporting characters in his work. She played Wendy in two episodes of Dollhouse, firstly the unaired pilot Echo and then in season one finale episode Omega. Like Reed Diamond, she also turned up in Much Ado About Nothing, playing the role of Hero's maid Margaret.
