This is phenomenal news. I've never had the opportunity to see any of these films...and they've been high on my list for quite some time.
As for the remaining Billy Wilder films, I've been dying to see these on DVD. I cannot for the life of me understand why Universal has not released them yet. They have released boxsets from far less-acclaimed directors.....and sets of films that are far less important.
I would love to see Criterion get their hands on some of these....how about this idea? - "Billy Wilder: The Screenwriter Years" which could focus on his pre-directorial efforts that are not yet released on DVD.
"The Lottery Lover" - 1935
"That Certain Age" - 1938
"What a Life" - 1939
"Arise My Love" - 1940
"Hold Back the Dawn" - 1941
Of course you could soup it up with (I would gladly double-dip to have all of these titles in one concise collection)
"Bluebeard's Eighth Wife"
"Midnight"
"Ball of Fire"
& "Ninotchka"
