She also directed Mother's Amnesty International "you are powerful" spot in October 2008, which won a silver at Cannes, and Sony's "twilight football" ad. More recently, she shot "poodle loop", a film for Nokia's new music app, through Wieden & Kennedy.
Gehrig has also worked as a music promo director, directing films for Plan B, Goldfrapp, The Noisettes, Basement Jaxx and Junior/Senior.
The move reunites her with the production company's founders Tim Nash, Sally Campbell and Nick Gordon, with whom she has previously worked. Somesuch & Co will represent Gehrig in the UK and internationally through its association with Caviar.
