For those with Starz on Demand, there is a lovely little video featurette explaining the background to the ongoing Da Vinci's Demons 'Book of Leaves' storyline. It has brief but briliant interviews with Tom and also David S. Goyer.
Another interview with the series creator can be found on the Citizens of Florence iPad app, and now on You Tube (US only) where he gives insight into the recently broadcast episode 4 - The Magician. Composer Bear McCreary has a brilliant blog about The Magician score, but don't read until you watch the episode.
Crave Online has shared a lovely review for The Magician, and especially for Tom's performance!
