Regarding "lookalikes", Colin Firth and Helena Bonham Carter look nothing like King George and Queen Elizabeth but "The King's Speech" has already won many accolades and has been nominated for 12 Oscars.
The movie was excellent because it did not sandbag the king and queen. There is no point to doing that to the royal couple.
However, doing a hit job on the Thatcher Legacy is the kind of thing one would expect from Hollywood Miscreants and British leftist scum. I won't see it even if it is on TV!
