Over at the Model Shipwrights web site, a proposal has been made for a group build with the theme "Hollywood at Sea". Any fictional ship that sailed on the big or small screen. Plenty of time to plan since the build does not begin until next September, 2008. There's even a very extensive list of suggestions there.

I'm thinking of trying to get hold of an old Nautilus kit and do the Tigerfish from "Ice Station Zebra".
