IMDB's listing for 24 has a section for goofs spotted in the first four seasons. Now punching holes in the "plot" of 24 is about as easy as Behrooz's dead ex-girlfriend.
It'd be too easy to note that the cell phones used on 24 never lose a signal, drop a call, or need charging. I cannot play Texas Hold'em on my phone for more than 30 minutes without losing a charge, but Jack can yell into his cellphone for 18 hours of a 24 hour season without charging.
Last season I noted the superhuman speed at which some of the cast are able to move, except for Edgar of course. IMDB notes the speed and a few others over the previous 4 seasons including:
You can check out the rest here.
-In season 2, episode 5:00 - 6:00, immediately after Kim kills Gary, she's talking to Jack through her phone, a Nokia 3650. The only problem is, she's holding it upside-down
-In Season 4, Hours 10 PM to 11 PM, when Jack shoots Nicole through the wall, as her dead body slides downward, a blood stain is visible on the wall. But as the camera follows Jack down the stairs to inspect the body, the stain is gone.
-In Season 4, the terrorists attack a military convoy in "the mountains of Iowa". There are no mountains in Iowa.
-At the beginning of episode #2.5 (12:00pm - 1:00pm) Jack drives back to CTU Headquarters near downtown Los Angeles from Joseph Wald's house in Simi Valley and arrives at 12:09pm. Simi Valley is 45 miles from Central Los Angeles, which would make it impossible to drive in only nine minutes as Jack's average speed would have to have been 300 miles per hour.
