Some extremely revealing news has surfaced from an unlikely source. Website 3D Focus caught up with Markus Lanxinger, the Lead Stereoscopic Engineer on Lionsgate’s forthcoming Texas Chainsaw 3D, directed by John Luessenhop for release on January 4.

Texas Chainsaw 3D continues the legendary story of the homicidal Sawyer family, picking up where Tobe Hooper’s 1974 horror classic left off in Newt, Texas, where for decades people went missing without a trace.

Within the following interview bits, Lanxinger reveals some shooting issues, talks about post converting archival footage, and how the slasher originally received an R-rating. Read on for the skinny!

Laxinger first told the site that the filmmakers were extremely worried about the fans calling out the studio for cashing in on the franchise to make a quick buck. He says they couldn’t be more wrong as this “sequel” was made for the fans: “We felt quite a bit of responsibility on set. The producer and the director were very concerned about it. For that reason they had some of the original cast enrolled in the movie. Everybody on the crew was required to watch the original [Texas Chainsaw Massacre]. I think that inspired us to do something that lives up to it. I could tell that the producer and director wanted to make something that appealed to the fans of the franchise.”

The site doesn’t provide any quotes, but states that, according to Markus, the schedule was tough. The entire filming process was completed in a 28 day 2D schedule. The Cinematographer allegedly had to be replaced towards the end and Markus unexpectedly had to take over the second unit as Stereographer. In order to complete the filming in time, the cast and crew switched to a 24 hour schedule.

The biggest reveal comes when Lanxinger speaks on post-converting footage to 3-D where he drops the bomb: “There were very few shots that we ended up converting on that film and the ones we did tended to be the archive footage and stills from the original movie.” Yes, there are scenes from Tobe Hooper’s original 1974 Texas Chain Saw Massacre in the 2013 sequel!

Speaking in regards to the film’s rating: “It initially had an NC-17 rating so we recut the movie and it got an R rating. There are certainly some gory elements but I also think there is quite some suspense in the movie. I think in America it’s very easy to get an R rating for violence and blood scenes. There are plenty of those but there are also moments where it is just scary with a suspense build up so I hope some of those scenes are going to stand out, not just the gory scenes.”
