Two of the finest comedy actresses currently staining celluloid, Elizabeth Banks and Leslie Mann, are to finally star in a film together. While both appeared in 40 Year Old Virgin, they didn't share any screentime, and now that their stock has risen considerably they will headline their own film, namely the comedy What I Was I Thinking? Film is based on the novel of the same name, that see's a bunch of women head off to a ski resort, after one of their buddies is dumped at her engagement party. Apparently Banks will play the dumpee, while Mann will portray a pal with commitment issues. This could very well turn out like Sex and the City style drivel, or it could be comedy gold; let's hope the two stars are given the script and director their ability damn well deserves.
