Filming on the 'Alexandra Shackleton' at Portsmouth on 22.8.2012

Curious to know what was being filmed, I Googled the only information I could glean from the photos, that I took while boarding the Portsmouth Harbour tour boat, the name 'Alexandra Shackleton' and this is what I found www.jamescairdsociety.com/latest.php So the film is 'Shackleton's Captain'
Sorry about the railing - we were literally boarding the tour boat. The shot at the lower right was taken from its upper deck.
