Gary Shore is probably the least known name on the list. He has, however, already directed a trailer for the film. I should note that no part of the movie has started production, so the trailer was probably made on spec as part of a campaign for the job. Its interesting and may just be a preview for what the movie will ultimately be like.
The trailer for Shore's directorial debut, The Cup of Tears is also worth a look. A full length version of this would probably look a lot like Sucker Punch, but the trailer is pretty neat. Like the proposed new Wolverine movie, it features a bunch of ninjas fighting robots.
