Why did they not use the tv sound fx in the
Doctor Who peter cushing movie it would been
so much better if thay had

I believe it was from the outset.The BBC were very good at protecting it's musical copyright then as now.

I don't know but I've always wandered this myself. Copyright seems unlikely, given everything else is in there

At a guess, I'd say it's for the same reason why the interior of the TARDIS had no central control console, "Doctor Who" being human and the tv theme tune not being used - perhaps because the programme was still quite young and hadn't firmly established itself yet so the film makers thought that they could fiddle with the concept somewhat. 

I seem to recall that in the first few years of the TV run, the TARDIS sound effects weren't always used, with the box just appearing and disappearing with no sound whatsoever.  In fact, didn't the materialisation sound effect come in rather late, around Troughton's tenure?

Just a thought.

the demat noise was always used; however the Ship used to land silently until around the War Machines, after which the demat noise was used to signify landings as well.  The first landing FX as is used nowadays happened as a one-off in the Krotons when the TARDIS uses it's HADS, and was used occasionally from then on to signify "different" materialisations (eg: the end of The Invasion when it becomes visible again) until Pertwee's time, when it be came almost standard, although sometimes it retained an extra "vworp", as in "Planet of the Spiders".  The noise continued to be altered almost from story to story, with Logopolis being the last time it missed off the end of the landing (1st landing, next to the Police Box).  After that the noise became almost standard with just the three or four vworps (although the last few McCoy Classic seasons used only the last two vworps by and large), notable exceptions being when others tried tofly the Ship, like Adric piloting it in the Visitation.

The New Series has reinstated a much longer TARDIS materialisation noise mostly, which gives a better effect.

Just to add the Tardis sound is officially classed as a piece of music ,not a sound effect and the film producers would have to pay an extra royalty to the BBC for it's use.

Was it classed a piece of music in the 70's or 80's?  Or was it classed that from the beginning since it was created by the Radiophonic Workshop?

I think it was the seventies when the BBC classed the tardis sound as a piece of music probably because of what was used to create the sound originally.

Interesting. Back in 1984 (I think that was the year) on one of my early ships, and when no one really cared, the crew used to show "those movies" on the night before we returned to home port. (I never bothered with that - couldn't see the purpose of it.) But I walked onto the mess deck for a drink just as they started this particular movie, and right at the very beginning there was the unmistakable sound of the TARDIS' final stages of dematerializing! I thought they were showing a 'Who' episode. Imagine my horror when I looked at the TV and saw... what I saw.

I went straight to sleep after getting my drink, but now I'm wishing I'd gotten the name of that movie so I could notify the BBC. I'm sure that movie is still out there someplace and I think the Beeb would love to sic their lawyers on that.
