Angela Lansbury's team has since spoken with EW and confirmed that she will NOT be joining the Game of Thrones cast for Season 7.
As Game of Thrones continues on past the content in the books, the pressure seems to be greater than ever for the filmmakers to deliver a worthwhile experience -- one that could stand toe-to-toe with any content that writer of the series, George R.R. Martin, could produce. After all, this is a series that's required a hefty amount of emotional investment from its fans. From its twists, turns, and unexpected deaths, it's a show that always seems to be competing against itself in terms of shock factor and general all-around quality.
While the details have been limited, we have gotten a few reactions from actors on the script for the season, as well as its first casting rumor in Harry Potter and the Half-Blood Prince star Jim Broadbent. Well, you can add another thespian to the cast list, for Bild is now reporting that Murder, She Wrote star Angela Lansbury is in talks to join in the fray.
As with Broadbent before here, there is no information on what role she's in talks to play, though I've heard a few outlets say that Bild specifies a "cameo" role, but I can't verify that myself. Regardless she's certainly an actor who lends an extra air of credibility to the franchise to its closing seasons -- though it's not as though Game of Thrones is in desperate need of credibility at this point.
Apart from being a continuation to the convoluted and epic tale of family rivalry of Shakespearean proportions, Season 7 is notable in that it will only be 7 episodes, instead of the normal 10. Given that the writers of the show were likely only given the major plot points for the rest of the books, this reduction in episode count will likely prevent any inadvertent filler they'd likely fill the show with.
Between this and the solid casting thus far, I'd say Season 7 is shaping up to be another solid entry in the series.
Game of Thrones returns to HBO next summer.
