- SRK for Bing Crosby (light-hearted gravitas)
- Kajol for Rosemary Clooney (goody! pair 'em up again!)
- Saif for Danny Kaye (comic timing)
- Preity for Vera-Ellen (although, we need a really spectacular dancer here...)
- Big B for the General (the audience would be in tears during the tribute at the end!)
And I think Karan Johar would be all over the melodrama of the plotline... what do you think?
