I noticed that many parts of the story of Prison Break match with the script of The Shawshank Redemption:
- an innocent sent to jail
- making friends in jail
- making wardens as friends on the basis of knowledge
- sneaking through the jail with digging out
- going to Mexico after breaking out of jail
Can Prison Break therefore be regarded as a copy of The Shawshank Redemption or are there at least any further references (or maybe even official statements) suggesting that this movie was a strong inspiration for Prison Break?
