(Note: I haven't provided links to any of these, as, evidenced by the different styles shown here, there are numerous editions available).
Here's a trailer from the original series, one of my favorites:
There's also a book written by Robin Ellis, who played Ross Poldark about the making of the series as well as the details behind the never filmed third season and a bit about Robin Ellis's career after Poldark, including his current career as a cookbook author. For more about Robin Ellis, visit his website. (He's going to have a part in the new series).
The new series will air in 2015 and will feature Aidan Turner as Ross Poldark. Here's a video (about the last Hobbit film) featuring Aidan Turner (as well as Richard Armitage and Dean O'Gorman, who alas, will not be in the new Poldark series. I adore Richard Armitage. If you haven't seen North and South, I highly recommend it).
I'm really looking forward to this new Poldark series. For now...back to reading the books.
Have a great day!
