As per what is written in Scripture; this story is written to be as close to Scripture as possible and as historically and theologically sound as I know to make it.
This being said though, events in the plot line that we don't know of from the Scripture (or history) are also part of this story. (We don't know what happened to Nicodemus, Joseph of Aramathea or much about Pilate.) So yes, there is some poetic license taken with events and personalities that we can only speculate what their interactions in real history actually were. For example, I'm sure the Roman authorities did do some investigation when they found out the tomb was in deed empty.
