If you are interested in Bhagvad Gita I recommend watching this episode of Mahabharata [1]. It has English subtitles.
On a slightly different note, these episodes (essentially, plays) didn't capture some of the spirit that the book shares. The book is more sombre in my opinion, it informs the reader of the things that happened (albeit in a Hardcode history - like manner, very fantastical and poetic), and it doesn't offer any pre or post-amble. A drive-by epic, if you'd like.
