A few weeks ago Warner made Season 3 available on DVD
exclusively as a manufacture-on-demand (MOD) title from The WB Shop online store, and not long afterward a fellow from Ireland named David asked on Twitter
about further releases. On August 2nd the folks at the Warner Archive group tweeted a reply
that had this hopeful information!
"Look for S4 of Old Christine around Christmas!"
Very nice to hear, by way of a heads-up. Thanks to reader David Buchanan for pointing us toward that post. Stay tuned for further info, including a specific availability date, once Warner formally announces it.
