What is the longest, single take, tracking shot in cinema/TV?

There have been movies where the entire movie is a single take.

The best I can find based on quick research are Russian Ark at 96 minutes, and Timecode at 97 minutes. Timecode is actually a quad-split screen film (four different videos running in four different quadrants of the screen), each of which is a single take shot, running for the entire movie. I included Russian Ark if you wanted something that has a more direct narrative and doesn't change focus to a different story in a different part of the frame by upping the audio track for that frame.

Update: Had I bothered to look a little further down in my Google search, there is evidently a new king for longest single take film. It's a Swedish film called 7333 Seconds of Johanna. The film is 2 hours, 3 minutes, and 3 seconds long, and was filmed with Guinness World Record officials present the entire time.

I guess the key here is using the word film in your title.

With film you are limited to the length in a canister and no amount of creativity can change that. With digital video this constraint goes out the window. So for film, it looks like Snake Eyes wins at just over 13 minutes. For digital video, Agadam looks to be a clear winner, endorsed by the Guinness Book of World Records at 2 hr 3 min 30 sec, beating out 7333 Seconds of Johanna by 27 seconds.

EDIT If @NapoleonWilson is correct, and DePalma used cuts, then The Player – Opening Shot: 8 minutes, 5 seconds might be the winner, and I hope it is, because it talks about other opening shots during the shot.

All these directors owe a debt of gratitude to Hitchcock for trying it in the first place. Rope was a very difficult and singular goal to strive for and he did a remarkable job given the technological and financial hurdles he had to overcome.

2015 saw the release of Victoria, in which the entire 2 hours and 18 minutes of action takes place in one uncut take.

• Scorcese's Copacabana tracking shot in "Goodfellas" needs mentioning.
• This ten-best tracking shots list from AMC lists the opening of "Snake Eyes" as being 13 mins.

I don't know "The longest shot" in all of the movies but I remember this movie Children Of Men directed by Alfonso Cuarón which has few long shots,

The length of the long takes: Long take in the car when Julian is shot - 3:58, Long take of the birth - 3:11, Long take of the siege - 6:18.

And Quentin Tarantino has a way of filming long shots.

His films will often include one long, unbroken take where a character is followed around somewhere.

It's not longer than the movies listed above, but the TV show Mad About You had a single take, commercial-free, 20-minute long episode called the "The Conversation". I haven't seen it since it was aired, though, so I don't remember if the camera was fixed or not.

There was an episode on the Third Watch TV show, that, as far as i can tell, was made entirely on a single shot. That is, about 43 minutes.

In fact, I usually never watched the show, but I started wathcing that one episode, and the fact that the first minutes had a single shot caught my eye, I kept looking it, and the whole episode was one single shot! Single camera, tracking among all the characters.

The episode was "A call for help"

Or at least it had VERY good editing, because you never notice if they change something.

update:

I've found out that it indeed was made on long shots, in ten minute loops without cuts. I guess each loop was sepparated by commercials on TV.

nonetheless, it was a nice episode, you don't usually see more than a couple minutes of single takes/shots in either TV or Movies.

There's a horror movie called Silent House, I think there's two or three cuts in it but they are all pretty cleverly hidden, besides that the movie is a continuous shot, probably about 30-40 minutes at a time.
