HELL, yes! That’d (somewhat) make up for his not getting to be James Bond.
Love Idris Elba, but Benedict’s description doesn’t even come close - he’s supposed to be scarecrow slim for one thing. However I admit to a bias as I had the Illustrated Zelazny as a kid with all the Prince trumps as done by Gray Morrow from the book descriptions. As a result I pretty much have those images fixed in my head, so any Benedict that doesn’t look sorta like that is a fail for me ;).
Not to mention the one major Christian in the book gets stuck in a pseudo-villain role ( i.e. Nirriti the Black ).
Those are from the '70s, right? In the 21st century, I think the characters should not look like they’re in prog-rock bands. 
Blame Zelazny! That’s exactly how he described the trumps and their layout in the first chapter. But yeah, he was writing them in the 1970’s :p.
Whereas in the Visual Guide to Castle Amber, Benedict looked like Samurai Jackson Browne (and Corwin looked *exactly *like an underrated James Bond).
Corwin…Josh Hartnett
Oberon…Bryan Cranston
Flora…Katie Holmes
Fiona…in a nod to GoT, Emilia Clarke
Gèrard…Steve Austin
Random…really like the idea of Jamie Bell
Benedict…another Benedict, Cumberbatch
Caine…Eddie Redmayne (no, not Random)
Julian…Rupert Everett
Deidre…Isla Fisher
(and no, I didn’t see the trailer till after this…)
Looks like some illustrator was aFlash Gordon fan…just gave him a shave :).
…and to shoot down the concept even more, the hero changes bodies!
Carnivorous Plant: From memory I believe the bird, Garuda?, was mechanical.
Thank you.
Good point, more actors, higher budget.
Dammit, I want to hear “And then the fit hit the Shan” on the big screen!
