Here is a 70mm frame with a TODD-AO title on it.

Here it is.

I've seen that on the opening credits for some film from the 1970's. One in particular was "The Asphyx" (1973). The opening credits said 'Filmed in TODD-AO 35' I think. What does that mean? BTW, some of my favorite horror films came out of the U.K. in the early 70's.

Todd-AO 35 was a anamorphic system not to be confused with Todd-AO 70
Some of the films were blown up to 70 mm prints
Like Logan's Run and Jesus Christ Superstar
Antony and Cleopatra

Yes TODD-AO 35mm was a big swindle and a waste of time.

Mike Todd ... The guy with the hairy arms.

And the cigars
And being married to Liz Taylor

Don't really know anything about it other than he was a showman and married to Liz Taylor.

Yes Mike Todd was one of the many who were married to Elizabeth Taylor. As for me I turned her down for obvious reasons.

Thank you Tony, for your answer.
