What are the differences between Matthew's and Luke's passion stories?

Some differences between Matthew and Luke's story of Jesus' trial and execution: * In Matthew, Pontius Pilate delivered Jesus to be crucified, and washed his hands. In Luke, he gave Herod of Galilee the responsibility of deciding Jesus' fate, and so did not wash his hands. * At the moment of Jesus' death, Matthew says that there was an earthquake and that dead people rose up out of the graves. Luke recorded no earthquake or resurrection of dead. In Matthew 26:69, Jesus was not present when Peter denied him.

In Luke 22:61, Jesus was present when Peter denied him
