Duplicate episodes in different series

Ray Bradbury Theater “A Touch of Petulance” and Freddy’s Nightmares “Judy Miller, Come on Down” both had characters go back in time to try to keep their past selves from murdering their spouses. (The latter featured the last performance of Susan Oliver, so I guess this could go in the "spotting Star Trek actors thread too.)

Both took the same plot as The Well, where a race riot is averted to rescue a girl who fell down a well (which was the root cause of the racial animosity).

I seem to recall that The Mod Squad and Charlie’s Angels (both Aaron Spelling productions) had episodes built around traumatic amnesia of one of the characters (Peggy Lipton, Cheryl Ladd?)and them being hunted by the bad guy while trying to regain their memory. If I recall correctly, the episodes were beat for beat alike and even had some of the same dialog.

Reminds me of an episode of Mannix in which Joe was disabled and had to deal with it while still a target for the bad guy. Except he was temporarily blinded instead of losing his memory.

At the end, he beat the bad guy in classic Wait until Dark style before regaining his vision. (Hysterical blindness, maybe?) I wonder how many times that’s been done?

This sounds a lot like an episode of Monk. It’s Monk Can’t See a Thing.
He was temporarily blinded. He encounters the bad guy, while still not being able to see. Just in time his vision starts coming back and he was able to beat the bad guy.

There was a fad in the 90’s to have a ‘Door #1, Door #2’ episode. Malcolm In The Middle did ‘Lois goes to bowling alley with kids, Hal goes to bowling alley with kids’. Frasier did a similar episode as did Veronica’s Closet.

I believe they were all inspired by the Gwyneth Paltrow movie Sliding Doors (1998).

Just what I was going to say - the Frasier episode was even called “Sliding Frasiers”

Bellisario reused a lot of footage from movies for his show JAG. I think the pilot ep lifted Top Gun footage and the most obvious reuse (to me) was when he lifted a whole scene from Clear and Present Danger.

There was also an episode of the Bad News Bears TV series in which one of the kids needs to replace a Johnny Bench autographed baseball that they lost. So they lure Johnny Bench to them to get it autographed by…one of them pretending to be deathly ill.

I seem to recall Starsky & Hutch and Charlie’s Angels both doing episodes where a convict escapes from prison, kidnaps the cop who put them away (Hutch/Kelly) and injects them with heroin, so they get to feel the agony of withdrawal.

The Time Tunnel did this all the time. Two examples that stand out in my mind are the one with the sabotaged space mission (set in 1972, IIRC!), which used the Luna scenes from Destination: Moon, and the “Trojan Horse” episode with footage from 300 Spartans.

Another is the one about the Alamo, with scenes from (You guessed it!) The Alamo.

eight is enough parodied that with Nicholas stealing and hiding the neighbor’s cat so he could get arrested because all the other 7 had done so and he wanted to experience it

In the mid 1970s, McCloud, Starsky & Hutch, and The Hardy Boys and Nancy Drew Mysteries all did episodes in which the detectives hunted a killer who thought he was a vampire.

True (I love that episode of S&H) but IIRC, the Hardy Boys one had the twist that he actually was a vampire (or at least, he didn’t cast a reflection…)

As opposed to Kolchak, where the killer actually was a vampire?

Rugrats had a similar plot with chuckie wondering what life would be like if he was never born i esnt to say it was called chuckies wonderful life

While not a similar plot i recently learned several shows brady bunch and different strokes being 2 of thwm added younger characters to tey and boost ratings and save the shows

Banacek was a TV show starring George Peppard as a detective who solves ‘impossible’ mysteries. The episode No Stone Unturned involved the vanishing of a big, heavy statue that couldn’t be moved without a crane. It turned out that the statue was actually an inflated balloon. The thief just deflated it

Blacke’s Magic was a TV show starring Hal Linden as a detective who solves ‘impossible’ mysteries. The Episode Ten Tons of Trouble involved the vanishing of a big, heavy statue that couldn’t be moved without a crane. It turned out that the statue was actually an inflated balloon. The thief just deflated it

Don’t think this one’s been mentioned yet:

On The Andy Griffith Show, Gomer Pyle becomes Andy’s devoted servant after Andy saves his life The only way Andy has to get Gomer off his back is to stage an accident Gomer can “save” him from to even things out. (Of course, Gomer would fail miserably if left on his own, so Andy has to give him a surreptitious hand.)

Exactly the same scenario played out with Gomer and Sgt Carter in Gomer Pyle, USMC. Hardly surprising, considering the latter was a spinoff of the former. There were probably other such recycled scripts, but I don’t recall them offhand.
