Aisha N Tyler (Tietjens)

A superb improv comedienne who made Talk Soup a must-see during her tenure as host, Aisha is also both a tech / video game aficionado and a serious home brewer, making her a fanboy fave as much for her magnificent mind as her bodacious bod!
She was also a multi-ep guest critic on At the Movies Ebert & Roper, easily besting Richard Roper in both analysis and cinema knowledge!
If only she wasn't already married... ;-(

Linda Park

Most of Linda's work has been genre films or tv! (Not that I'm complaining...)
Regular cast member on four series, three of which were genre.
And, in my opinion, she's one of the few reasons to watch the first three seasons of Enterprise! (The fourth, and final, season was actually pretty good!)
Linda's a tae kwan do black belt and gifted ballroom dancer, as well as the founder of the Underground Asylum theater company.

House MD "The Fix"
Mentalist "BloodHounds"
