Tend, I am a big fan too of both Shackleton history and Ken Branagh. Yes, indeed there is a miniseries film and it is extraordinary in my opinion. I bought mine off of Amazon and last I saw it was not that expensive for the 3 disk set - it has tons of extras on the third disk - so it is well worth the price.
Oh my goodness, if you love Branagh you have to see this film! Well of course he is older in the film, but he still exudes such charm and likability. If you read back a number of posts I have written up a whole thing about the film. Actually I have written several posts about it to Kiz. She is interested in seeing it soon. See post #1616 for full Shackleton review.
I highly recommend seeing all the disks and all the extras, too. That will take some time, but if you are like me you will get addicted to the story. I have now read about 3 books on the expedition and I bought a huge coffee-table size book with fabulous pictures by Frank Hurley, the Australian expedition photographer; it is a miracle, in itself, that these photos and films survived.
*Here's a tidbit. When Sturridge asked Ken to star in the role he had no script and no backers yet, and Ken immediately accepted the role. It is good he did, he was up for an emmy for his fine portrayal. I was sorry he did not win - but sometimes they don't have good taste; forget who beat him out that year. Also, Ken meet his second wife while filming Shackleton. Is that cool or what? She is on the extra disk - "Making of ....", assistent art director, I think.
Tend, I just checked Amazon. In the US you can order it for 9.32 from a seller and they have 99% positive - says brand new. Here's the main link to the film in Amazon:

"Blades of Glory" - Tend, who stars in that film and how old is it? I know I have heard of it before.
