I was already familiar with the story of Cyrano from the French film featuring Gérard Depardieu as the classic poet. But it wasn't until seeing this that I was completely captivated by the story. The whole play is charming, but it was Kevin Kline as the title character that I fell in love with - his performance is big enough for the theatre, but subtle enough to be watched pleasingly on DVD; his talent for comedy is displayed often, as is his incredible gift for drama - my favorite scene remains the 'balcony scene', followed closely by the finally (I would say more why I love them, but it rather spoils the fun of seeing it yourself!).
Jennifer Garner plays a very sweet Roxanne, though her performance is much broader than a film performance would be (but of course, since it IS a recording of a stage show) and so is rather awkward at times on film.
Daniel Sunjata plays the lovestuck Christian, and gives an admirable performance.
