Then: Tannis Vallely played Janice Lazarotto, a 12-year-old prodigy who was able to outshine her older genius classmates in the sitcom 'Head of the Class.' Previous to that, Vallely appeared on the PBS show '3-2-1 Contact.'

Now: Vallely proved she was pretty smart in real life too by attending Stanford. The 36-year-old now works in casting on movies like 'Oceans 13' and 'X-Men Origins: Wolverine.'  Her only post-'Head of the Class' on-screen role was her appearance on 'Arrested Development' as -- what else? - a casting director.
