Displacement

  • written and directed by Kenneth Mader
  • (Boston SciFi Film Festival, 7 February 2016)

Brilliant physics student Cassandra Sinclair finds herself running from the evil Initiative Organization—which includes her childhood friend Josh and a posh lady with an English accent—who are after the equations in her thesis notes that somehow (she’s not quite sure how) launched her on multiple slips back in time (we counted eight) that may or may not result in destroying yourself by getting too close to yourself, a closed timelike curve, quantum entanglement, and/or solving the Grandfather Paradox (without ever having anything that resembles the Grandfather Paradox, quantum entanglement, or a closed timelike curve). We suspect that writer/director Kenneth Mader had been reading “Experimental Simulation of Closed Timelike Curves,” but the actual science didn’t fully translate from the lab to the silver screen.

Handy Hint: The movie is eminently more watchable in a late-night group where everyone shouts “Great Scott!” whenever a character spews a sequence of pseudoscientific quantum mumbo jumbo that vaguely resembles an English sentence. —Michael Main
We’ve been running simulations to resolve the Grandfather Paradox, and we experienced an unusual electromagnetic pulse at the school that was triggered remotely. We were able to locate the source, but I suspect someone may have taken our simulations a step further. . . . The equation in your daughter’s thesis notes may have actually solved the paradox. But they’re untested and now they’re missing, and you said Charles has been absent. Could he have taken them and induced an entanglement?!

While roleplaying as a 19th-century lady’s maid, vigilant FBI agent Kate Donovan finds herself thrown back to 1815 England where she fights the norms and mores of the time and solves a serial murder case. She hopes that solving the case will prompt her to be thrown back to the 21st century, but alas she seems fated to stay where she is to star in a series of mystery books along with her 19th-century host, the Duke of Aldrich, and his marquis nephew, the debonair Alex.

See You Yesterday


Up in the ITTDB Citadel, our first attraction is naturally to the time travel aspects of any movie, even when the result is an incomprehensible time wreck resulting from a pair of teenage geniuses. That’s what’s on the surface here, but it also seems to be a metaphor for the even bigger train wreck of the racist society in the 21st-century United States. —Michael Main
You’re missing the big picture here: If time travel were possible, it would be the greatest ethical and philosophical conundrum of the modern age.

The Future of Another Timeline

On the surface, the Daughters are time travel scholars, but in reality, Tess and her fellow Daughters are fighting a pitched changewar for women’s rights against the oppressors known as the Comstockers. One more thing: While she’s at it,Tess also hopes to also save the souls of her teenaged self and her underground feminist punk friends in the 1990s, with a particular focus on their vigilante killing spree and young Beth’s abortion. —Michael Main
