A surprise to find them, but they are both available for purchase on Amazon Streaming.
I bought both of them $9.99 a piece.
Sadly both are 1.33...and from a very old source...practically looking like public domain titles.
I have been wanting LOVE WITH THE PROPER STRANGER ( Natalie Wood and Steve McQueen) for years and I can't believe it has still not been restored and released on DVD or Blu.
OH DAD...a botched film version of the Arthur Kopit play with Rosalind Russell, Robert Morse, Barbara Harris....and Jonathan Winters ( who a year after it was shot..added a terrible narration and inserts). Paramount was have been very nervous about the original version...and made it worse wiht their tampering.
