College Speech Idea Help - $10 prize to winner ASAP

I have to make a speech tommorow on "examine a retelling of a narrative to determine why the re-teller made the choices he or she did while writing/creating the second work of art."

It's similar to our first essay on The Glass Key by Hammett and Miller's Crossing.

What are some good easy retellings I can examine for tommorow? What are some books that were made into [censored] movies or great movies. Best idea will get $10 via pokerstars from me. I need this within the next hour though cause I have to make a good powerpoint.

Please herlp!
