Plot hole: The whole plot of this movie stems from a scientist selling his time machine to a corporation for further funding for development. He has a TIME MACHINE. Lotteries, stock market, 100 years of interest on a savings account. Why does he need more funding?
Visible crew/equipment: If you look at the ridiculous circus-looking mirror in the background of the CEO's supposed office, a boom mike lifts out of the reflection a little too late. It's in the shot when Nick is escorted away by security.
