Try reading Da Vinci and his mysteries. Also try out his painting books published by Penguin. Also, if you are so intrigued just by seeing the movie you should definitely read the actual book - because the movie showed none of the interesting facts about Da Vincis paintings - for example, I remember when I was reading the book I couldnt almost sleep after I read the description of the Madonna of the Rocks and the horrific images embedded in it - but the movie didnt pay attention to it at all. They only showed some scattered facts on the Last Supper. Read the book, you will be amazed much more.
