TV Legend Betty Buckley Joins ‘Supergirl’ @tvinsider https://t.co/zAxzuJPJtL

— Betty Buckley (@BettyBuckley) September 29, 2017

From Eight is Enough and Oz to Pretty Little Liars and The Leftovers, Betty Buckley has been bringing class and sass to the small screen for almost as long as she\'s been a Broadway legend. And now, the Tony winner, who originated Grizabella in "Cats" on Broadway, is set to make a new memory as Patricia Arias, the adoptive mother of Supergirl\'s villain-in-the-making, Samantha (Odette Annable).

According to The CW, the Arias women have been estranged since Sam became a teen mom and "their relationship is made all the more complex by the secrets Patricia holds." Given that Sam is actually Reign, the genetically designed, world-killing weapon we first peeped in May\'s season finale being sent to Earth from a cabal of hooded Kryptonians before the planet exploded, it\'s highly possible that one of those secrets the "honest, but stubborn" Patricia is sitting on includes the still-unaware Sam\'s otherworldly and lethal origins.

Buckley is set to make her first appearance in "Wake Up,\' the third season\'s seventh episode.

Every day 100\'s of items are submitted to us and we don\'t always have the time to make separate posts for the news and/or there is so much that it would quickly push all other items off the homepage.

So a result we\'ve come up with the idea of the Newsreel, which will feature smaller shows and news items as they happen.

There will be a new Newsreel each day, and as news is added we will update the post and and push it back to the top of the site so that you can see that new items have been added. A tweet of the item will also be sent to our @SpoilerTV account.

This will allow us to provide more news on more shows in a much more timely fashion

Rather that creating lots of new posts as new info is released and fragmenting the commentary, we thought it would be a good idea for the upcoming major movies to create a single post for each major movies that will collate all the info as it\'s posted.

New items will be added to the top of the list as well as the post being re-posted back to the top of the homepage when a new item is added. We will additionally send out a fresh tweet alerting you of the new information.

This will allow you to bookmark this page so that you can return to it whenever you like. It will also help consolidate all the discussion on this movie in a central place and make it less likely that you\'ll miss some key information.
