Continuity mistake: When Charlie is comparing a computer wipe to a data scrubber, he first crosses out the equation"E=MC2" with a magic marker, beginning mostly with uniform, vertical lines, and then lightly scribbled. However, in a later shot in the sequence, the cross-out is different, being mostly scribbled, with few vertical lines.
Numb3rs (2005)
1 continuity mistake in Sacrifice
Starring: Judd Hirsch, David Krumholtz, Rob Morrow, Alimi Ballard
Continuity mistake: When Charlie Epps is writing a quadrillion on the whiteboard, the writing alternates between shots. Most noticably when he first writes it down, there is a significant downward tendency of the 000 groups. In the next shot, they are pretty much horizontal. Also the shapes of the commas alter.
Charlie Eppes: Everything is numbers.
Trivia: Judd Hirsch is an astro-physicist and can actually do the math Charlie does on the show. He caught the acting bug in school and chose that over physics.
Question: This question is about the mistake where a SWAT officer has a magazine backwards in his MP5. I know this would be impossible on a real weapon. But, how could it have happened in filming? Rubber cast weapon? Very badly worn prop weapon? Set armourer with a hammer and no clue?
