Cashback is a 2004 short film remade into a 2006 feature film, written and directed by Sean Ellis.
Ben (Sean Biggerstaff, Oliver Wood from the Harry Potter films) is a wage slave working the night shift at Sainsbury's, a 24-hour grocery store, earning money to put himself through art school. Among his co-workers are the lovely Sharon (Emilia Fox), goofy cut-ups Matt and Barry, and their irritating, overbearing boss Alan.
The workers at the supermarket find different ways to pass the time. Sharon avoids looking at the clock at all costs, even putting a piece of tape over her watch. Matt and Barry goof off all the time, doing things like having scooter races around the aisles. Ben eventually discovers that he has the ability to manipulate time. He can speed it up, but more importantly, he can freeze it. Ben the aspiring artist then starts undressing the beautiful women he occasionally sees in Sainsbury's and drawing them.
- Adaptation Expansion: The feature built a 102-minute story out of what was a 17-minute short. And since all the actors from the short film returned for the feature film, the short was incorporated in its entirety into the feature.
- Bilingual Bonus: After Sharon learns of Matt spreading a rumor that he slept with her, she insults him in Spanish.
- Call-Back: The film starts with Ben's breakup with Suzy playing out in slow motion. Later, after a misunderstanding with Sharon, her ranting at him is portrayed the same way.
- Chekhov's Gunman: Natalie.
- Europeans Are Kinky: Of course it's a Swedish woman guest strolling around young Ben's house in the nude.
- Facecam: On Barry as he's cruising around the grocery on a scooter.
- Fanservice: Lots of naked women.
- Fanservice Extra: Many. Porn star Hayley Marie Coppin appears as the naked Swedish exchange student. Keeley Hazell, one of the most famous Page 3 girls ever, appears in the feature only as one of the naked frozen women in the supermarket.
- Inherently Funny Words: Matt and Barry bust out laughing when an elderly woman at the meat counter asks for sausage.
- Knuckle Cracking: Ben unpauses time by doing this.
- Nice Job Fixing It, Villain!: Matt and Barry play a prank on Ben, with Matt calling Ben pretending to be an art dealer who wanted to feature his work. Ben only learns he's been had when he actually heads to the gallery, but the real art dealer is impressed enough with his portfolio to give him a business card. The movie ends with Ben hosting a show at the gallery.
- Power Perversion Potential: Well, he is using his time-stop ability to draw naked ladies.
- Progressively Prettier: Sharon is first shown in the film as a harried checkout girl. The more Ben interacts with her, the more attractive she appears as the story progresses. By the near-end of the movie, Ben devotes an entire art gallery to putting her beauty on full display.
- Protagonist-Centered Morality: In another setting, rendering women unable to consent and then stripping them naked so you can draw them, might be considered... bad. Here it's just part of Ben's artistic appreciation of female beauty. It's conveniently contrasted by his best friend Sean's unabashed lust.
- Sexy Scandinavian: The curvaceous student whose naked form triggered Ben's obsession with the female body is Swedish.
- Shameless Fanservice Girl: The Swedish student thinks nothing of strolling around the house nude while young Ben is around. Natalie counts as well.
- The Sleepless: Ben since his breakup. He decided to work at the grocery store because he had nothing else to do with what used to be his sleeping hours.
- Time Stands Still: Ben can make time stand still.
- Title Drop: Ben muses about how he gives the grocery 8 hours of his time and they give him money—"cash back". Later Sharon asks a customer if they want cash back.
- Video Credits: Of all the principals.
- Visual Innuendo: Matt and Barry note how a certain shampoo comes in a package that looks very much like a dildo. They set about surreptitiously putting bottles of the shampoo in women's shopping carts.
- What Happened to the Mouse?: In one instance while Ben pauses time, he sees a man running away from him, catching him by surprise. This is never addressed again in the film.
