A lovely and amusing film which really looks the business but is unfortunatley rather dull haha. As said the look of the film is truly brilliant, the costumes and sets all look great and really stand out.
The casting was very good, Clooney shows his quite surprisingly good prat falls and facial humour, his acting isn't topps but for this its sufficent.
Both Krasinski and Zellweger are also good choices for the era, Zellweger has always looked as if she's been kidnapped from the era but her acting is pretty dire. Krasinski is fine but nothing special, alittle too wet really. To look at they fit perfectly yet the acting isn't too good.
One scene where Clooney and Zellweger are escaping from a speakeasy raid by the police is pretty embarrasing really, corny, cheesy and terrible acting, it isn't much better throughout to be honest.
The whole thing is sweet and charming but its just dull and not very entertaining with dodgy acting, the great period looks save it.
