A few days ago, Warner Archive revealed it will be releasing
According to TVShowsOnDVD.com, although My Friend Flicka: The Complete Series has a release date of May 24th (that’s today) it might not be available everywhere for a few weeks. Also, an Amazon listing exists for the DVD with an August 23rd release date but TVShowsOnDVD.com has confirmed with Shout! Factory that the Amazon listing is a mistake.
Custer: The Complete Series will be released on June 6th.
Presumably, both of these DVD sets will eventually get a general release outside of Walmart, although I can’t confirm that.
