Time-travel rules in The Terminator franchise are notoriously inconsistent. Is it possible for someone from the future to travel backwards to change events, given the paradox that with a changed future, the traveler wouldn’t then have had the problem to try to come back and fix? Neither the closed-loop series of events in the first film nor the changed (postponed) future in the second make sense, and it just gets worse from there.
Mark, Erica, and Brian are joined by Brian’s brother and co-author Ken Gerber to talk through the various time travel rulesets and plot scenarios (a good starter list is at tvtropes.org), covering Dr. Who, Back to the Future, Looper, Dark (the German TV show), time loop films a la Groundhog Day (Edge of Tomorrow, Happy Death Day), time-travel comedies (Future Man), historical tourism (Mr. Peabody and Sherman), Timecop‘s “The same matter cannot occupy the same space,” using time-travel to sentimentalize (About Time) or clone yourself (see that Brak Show episode about avoiding homework), and freezing time (like in the old Twilight Zone).
