League of Extraordinary Gentlemen Tanks

Anyone seen this new movie with Sean Connery? They have these tanks that look like WWI British Tanks, but used by the Germans. It just made me laugh also because the year is 1899. Obviously some historical inaccuracies here…Anyone know anything about the tanks used in the movie?

They were definately modified tadpoles, I liked the retractable cannon in the front.
There were a lot of historical inaccuracies but it was a fun movie.
