Casting call--who would you like to see...?

OK, so say that a fairly well-known Titanic author had just completed
a screenplay about the BOT Inquiry, centering around the Californian
incident....

And say that there is a production company currently putting together
the financing to produce the film....

And say that you were being solicited for your opinions regarding who
should play what roles....

The only restriction is that the person(s) suggested can NOT have
appeared in any previous Titanic-related production.

So, who plays:

Captain Smith?

Captain Rostron?

Captain Lord?

Lightoller?

Boxhall?

Bride?

Cottam?

Stone?

Groves?

Sylvia Lightoller?

Sir Rufus Isaacs?

Butler Aspinall?

Lord Mersey?

Inquiring minds want to know!
