Continuity: When the group is deciding who cheated, the bottles and can on the desk change position throughout the scene even though nobody touches them.

Factual error: In the scene where St Matthews is Playing St Luke's in Football you can ADAMS printed on the chin strap of Matt Damon's Helmet. This movie was set back in the 40's or 50's and Adam's was not making those chin straps especially with ADAMS printed on the strap for many years to come.
