Who: London-based freelance film critic
Tweeter: Guy Lodge can really flip the writing switch. When he's penning reviews of higher-brow cinema (art-house, foreign, awards-bait, and so forth), the British critic writers with scholarly, elegant prose that, be warned, could fly right over the heads of casual readers. But when he's conversing with his peers via Twitter, Lodge loosens up and often lets his inner comedian come out and play.
