Better than average TV movie, but...

Mixes in actual NASA footage, even if it doesn't fit that particular scene!

Mission control was taped in the actual KSC firing room at Cape Canaveral - should have been at the MOCR in Houston, Texas.

Probably could fill a telephone size book with mistakes, but a couple that have always bother me;

Dark side of the Moon? Really? I guess it wasn't written by a rocket scientist! It's properly called the far side, and during the landing would have been nearly 50% lit by the sun.

Vacuum cleaner in the CSM? Hello?! In zero-Gravity, dust/dirt doesn't settle to the 'floor.' During the later NASA mission they had a paint brush to get the dust off their suits, but never a vacuum cleaner!
