Here are a couple more interesting movie trailers I found in the last couple days.
I first heard of The Legend of Tarzan courtesy of a comment a fellow writer made online. I forgot about it for a bit, then remembered it and hit YouTube to learn more. As far as I know it's been a long time since there's been any live-action Tarzan material--Casper Van Dien was in the box-office bomb Tarzan and the Lost City and there was a live-action WB television series featuring an American teenage heir to a corporate fortune instead of a British nobleman that if I remember correctly got canceled pretty quickly.
Based on the trailer the movie looks really cool. It seems to be set in the colonial era with all the steamships and Maxim guns (and even features the British Punch magazine from that era), but it also has all the unknown-civilizations stuff from an old-school Edgar Rice Burroughs story. Not sure when precisely it's coming out, but it certainly looks fun.
And now for the next one, which I was alerted to the other night by my friend Nick. It's a film adaptation of Roald Dahl's novel The Big Friendly Giant, which I remember reading in the third grade.
I like the trailer's style--they basically introduce the idea of giants and giants abducting people and end with the little girl saying that this is how the story begins. It's a good way of hooking the audience and getting them to want more.
