The last few Christmases I've uploaded Batman audiobooks. I've done Batman Returns, Batman Forever and Batman & Robin. So I'm out of movie based audiobooks.
I hope this one will be of interest (and won't get taken down). It's an audiobook called Legends of Robin from 1996 that loosely adapts various comic books arcs to show how Tim Drake took over from Jason Todd.
It's got a couple of interesting voiceover actors. John Shea (who played Lex Luthor in the TV show Lois and Clark) narrates the story and Mark Hamill (who voiced the Joker in the Batman Animated series) does the voice of the Joker.
Give it a listen and have a Merry Christmas. See you in the new year.
