5. Jim Broadbent in 'Arthur Christmas' (2011)

The film is still brand new, but we predict classic status for the cartoon and its clan of clashing Clauses. Besides Broadbent as a doubt-plagued Santa trudging toward retirement, there's also Bill Nighy as cranky, modernity-loathing Grandsanta and James McAvoy as young Arthur, whose eagerness and overabundance of Christmas spirit mark him as the heir to the sleigh.
