In this three part BBC drama (which was written by Russell T Davies) David Tennant played the famous seducer Giacomo 'Jack' Casanova. The older version was played by Peter O'Toole.
The description for this video is 'Jack continues to get lucky, almost gets married, and finally gets a kiss from the lady he loves.'
Casanova was broadcast in 2005.
