I'd love for Temeraire to be a series, in my head I had Tom Hiddleston as Laurence but he might be aging out as well. Though Richard Armitage would also have been awesome.
All I can think is that it would cost a boatload of money. Boats, war and dragons.
I'd watch it as an animated series, then it wouldn't matter how old Armitage or Hiddleston were.
I just saw a video on this. Sad to think that it's becoming a majority that live like this.
