Saw ET in the cinema 30+ yrs ago. There was a short movie – a dog being brought back to life –?

I can't even remember what I had for breakfast 2 days ago and you want someone to remember a short
go-no-where film shown before ET, 30 years ago?! There is not enough ginkgo biloba!

Try imdb.com.

Is it perhaps Frankenweenie? Debuted 1984. Stars a dead dog and his owner, a young boy.
