3. John Matuszak, who played Sloth, was a famously hard-partying former player for the Oakland Raiders
One of the film's most indelible creations was 'Sloth' Fratelli, the deformed but good-hearted Fratelli who ends up coming to the rescue of the Goonies. The character was played not by an experienced actor, but by John Matuszak, a 6'8", 280 pound former defensive linesman for the Oakland Raiders, known to fans as the Tooz. Matuszak had been the first draft pick back in the day, but his career had long been overshadowed by a hard-partying lifestyle, and heavy drug use (Sports Illustrated would later place him among the top five NFL bad boys). After spending the 1982 season injured, Matuszak turned to acting with roles on TV series including "The Dukes of Hazzard" and "The A-Team," as well as features "Caveman" and "The Ice Pirates," before he got the part of Sloth. The make-up took a whopping five hours to apply (with an eye that was operated by remote control), and if it got wet, had to be reapplied from scratch -- something that, as soon as they realized, gave Josh Brolin and some of the other young cast enormous power over Matuszak. The actor died four years later of a heart attack, thought to be caused by steroid use.
4. There was an entire deleted scene where the crew battle an octopus.
At the end, when Data tells his mother of their adventures, you'd be forgiven for being a little confused when he says that they fought off an octopus, despite that not having taken place in the film. The sequence, in which Data fends off the aquatic beast by putting a tape recorder in its mouth, playing the Arthur Baker-produced "Eight Arms To Love You," created especially for the film, was scripted and shot, but eventually trimmed. This caused some problems, as Baker and musical director Cyndi Lauper had hoped the song would be a big hit. As it turns out, it did become something of a dancefloor favorite, making it to number one on the Billboard Hot Dance Club Songs chart, and inspiring the odd stop-motion video below. That wasn't the only video that came off the album (which also included The Bangles and REO Speedwagon): Donner directed an epic, cameo-packed video for Lauper's theme-tune to the movie, "The Goonies R Good Enough," which included appearances from the film's cast, The Bangles, Spielberg and a selection of wrestlers, including Andre The Giant. Earlier this year, Lauper recorded a new version for an episode of Fox animated series "Bob's Burger" that pays tribute to the movie.
5. Nearly 30 years on, a sequel looks unlikely, but there may be a Broadway musical version soon.
"The Goonies" was a pretty big hit when it opened in June 1985: it was beaten to the top spot by "Rambo: First Blood Part II," but ended up in the ten top domestic grossers in the year. But for a long time, it looked like the closest it would get to a sequel would be the 1987 NES video game "The Goonies II." But as the film became an enduring cult classic, Donner and Spielberg came up with an idea, and met with writers, but no one could crack it: Donner told Empire at a cast reunion in 2009 that "We tried for a long time. Steven and I had many meetings... but nothing stuck. It seemed disrespectful... No hope." However, continuations in other mediums may be more likely: an animated series, which would see the adult Goonies passing the torch to younger kids, was in the works at Cartoon Network, but deals couldn't be signed with the cast. But a Broadway musical version remains in the early stages, with Donner telling Collider last year that, "We’re getting good outlines and good story. I’d say hopefully we’ll have a good script maybe by the middle of this year, around September or October, we’ll have a script that we can go to from there. It’s a long process, Broadway, it’s amazing. It’s frightening in a strange way. But we only get great reactions from everybody, everybody wants to see it. It seems like a great idea, and we’ll persevere. A musical of 'Goonies' on Broadway? But it’s gotta be irreverent, and it’s gotta be 'Goonies.'"
