invitation to the wedding be the last film of sir ralph richardson who play a somewhat dotty old bishop who accidentally marry his grand niece to a visiting american who be just stand in for the groom at a wedding rehearsal . it be release two year after richardson have die and it also feature that other classical act knight and sir john gielgud as well . it be a family joke that richardson have marry a butler to a member of the royal danish house under similar circumstance . and here the old boy do it again . but apparently richardson have a sense about these thing . because it turn out that visit american paul nicholas be really fall for bride susan brook and he get a week to make his case before the real groom jeremy clyde return . they must do thing differently in the united kingdom because i think they would have have to have a license first . but that aside the young lover and allegedly of college age and slightly over be all well into their thirty and even forty . they simply just do not convince me a young people in love . john gielgud be in the film a an eighty era reverend bring the united kingdom some of the billy graham school of evangelism . i be not sure what his purpose in the film be other than to be with a value colleague and friend for a last time . his role be entirely superfluous . however a a last look at thespian giant ralph richardson do deliver a great performance . to bad it have to be in such an ordinary film .
