No relation to the 1939 Claudette Colbert-James Stewart comedy of the same name, It's a Wonderful World is essentially a vehicle for British-based bandleader Ted Heath. The thinnish plot is set in motion by would-be songwriters Terence Morgan and George Cole, who manage to sell a tune by claiming that it was composed by a reclusive musical genius. When the tune hits the top of the charts, Morgan and Cole find themselves in the embarrassing position of having to produce the "real" composer. Director Val Guest manages to extract new laughs out of such old setpieces as showing a snobbish audience being gradually won over by pop music. The principal attraction of It's a Wonderful World--to modern viewers, at least is the presence of Ted Heath, whose screen appearances were all too few and far between. ~ Hal Erickson, Rovi
