When you've got three of the nation's best actresses in leading roles, it doesn't matter if your script is only adequate and the audience really has to squint here and there to believe what's happening on the screen.
There are zero surprises in the road comedy Bonneville, sadly including the fact that three middle-age actresses with three Oscars and nine nominations among them couldn't find anything more challenging to do.
Yes, the film deals with women of an age who are usually ignored in film, and it further deals with questions of mortality and loss, which are equally overlooked. The problem is, it doesn't deal with them very well.
It took brass hubcaps to make Bonneville, a midlife-chick-road-trip movie starring a '66 Pontiac convertible and a trio of middle-aged driving girlfriends in cool sunglasses, and not once have the gals give props to Thelma & Louise.
