The Costumes: Silk and other assorted glad rags: those Russians aren’t afraid to flaunt what they got.

The Constrictions: Marriage. Ain’t it a drag? Poor Anna’s trapped in a loveless union with her husband. Problem is, he won’t grant her a divorce – it just wasn’t the done thing back then.

So, even when Anna falls in love with Colonel Vronsky (a love that he returns), she must conceal their affair or face severe social penalties.

If They Changed Costumes: Pop Anna in a Princess Leia outfit, shove Vronsky in some Han Solo garb, and let them play out their romance against a starry backdrop. Could end happily this time (no trains in space).
