That could be, but I think there may be an alternate version. Here's an example; the first photo is from the theatrical version of Cheryl Rixon's Used Cars ENF (topless/skimpy panties), and the second photo is from the television version (bra/modest panties). It was extremely common at the time to shoot two versions.

Here are the two versions of the Animal House pillow fight scene. The first 2 photos are from the theatrical release (topless). The second 2 photos are from the television release (bras).

The Animal House photos posted out of order (because of the size). I'm sure that everyone can figure out which version is which.

Now you got me wanting to research this!

Here's a vid of the scene on YouTube: https://www.youtube.com/watch?v=lVXlVtVama4

Unfortunately, "costume underwear" in that version (now I'm using that term LOL). There's no free showing of The Survivors on Roku that I see. Hmm, seems we have a mystery: Was there a second, less family-friendly version of this scene ever shot?

But on topic of the scene, I love when super feminine good girls like that wind up in their undies.

The most extensively reshot film was probably 10 to Midnight. The film was packed with nudity (including full frontal). All the nude scenes were reshot for the television version, with the girls wearing bras and panties. This film has the most satisfying of all Charles Bronson movie endings (first photo).

Caitlin O'Heaney (who?) rare EUF still, from the film; He Knows You're Alone. She played the female lead on the short lived television show; Tales of the Gold Monkey.

More of Caitlin O'Heaney's EUF scene, from the film; He Knows You're Alone. Not an actress you often see unclothed (or clothed, for that matter).

Dangerous Curves TV Show
 

First off apologies for the dreadful quality of these images. My video source is from an old VCR(!) tape. I don't have a cleaner copy.

The show is "Dangerous Curves" and ran on CBS for two seasons in 1992 and 1993. It was part of the networks "Crimetime After Primetime" offering, an umbrella title for a group of late-night crime-investigation shows.

I guess the idea was to copy the "wheel show" format that NBC had with shows like "Columbo", "McMillian & Wife, and "McCloud" in the early 70's. Only this was targeted for late nights and contained racy material.

This was the era where bra and panties could be first be openly shown on a TV show. TV shows had been slowly working up to this since the 60's, and the dam finally broke in the late 80's.

There were a host of shows on cable and late night TV that took advantage of this. This was an era where "sexiness" was defined by attractive women in their undies or tight mini dresses, heels and hose, showing a lot of skin. Later, this definition would devolve in to showing cleavage on a 105 pound starved actress with a 44D rack job...or a supposedly nude girl in bed under the sheets...

Anyway, red head Lise Cutter plays an investigator at a security firm and comes across a shadowy character that could either be a foe or ally.

He pulls a gun on her at a hotel meet and has her strip off her dress to prove she's not wearing a wearing a wire. After she does so, he sticks her with a knock out drug and then leaves. A great scene!
