70s? British cartoon movie w/Jolly Roger
I cannot for the life of me remember the name of this movie. I'm pretty sure it was shown in the 70s as I was a small kiddo watching it. We had it on Beta tape I think...
British cartoon movie about a sister and brother who travel to a faraway land via their treehouse (I think). It's not called the Magic Treehouse cause apparently there is a series named that and it's all I seem to Google every time I try to find the name. The antagonist, from what I can recall, is a pirate - not sure if his name is Jolly Roger but he has a floating airship with the skull & crossbones flag. The ending has the kids returning back to their own world but the treehouse blows up and they can't ever go back - gah I hate getting old and forgetting this stuff.
I was so happy to find The Mouse and His Child that I thought my luck would continue with me remembering this one! Please help...
