A dinner party from hell or what? We quickly learn that hosts "Sarah" (Shirley Henderson) and husband "Tom" (Alan Tudyk) are having to sell their luxury home else face repossession. For some reason that seemed like a good reason to invite long-term friends "Richard" (Rufus Sewell) and wife "Beth" (Olivia Williams) round for food. It's the latter who throws a real spanner in the works by inviting the eponymous "Jessica" (Indira Varma). Let's just say that the hostess and this guest get on like a house that's already burnt down, and as the vino flows (tiny measures in huge great glasses) things come to an head that leaves the four with quite an headache. What now ensues might well have worked on stage, indeed the entire film has a theatrical style to it, but I found it all just a bit to hysteria-prone, contrived and over-dramatic. None of the actors are on especially good form, especially the lacklustre Tudyk and the script seems more determined to make sure each character gets their moment in the spotlight rather than designed to offer us something to laugh - or even smile at. On that front, there are the odd lines to make you titter, but just not enough of them to pass this feature-length more miss than hit sit-com. It will pass ninety minutes easily enough at Christmas on the telly, but nothing much more than that, sorry.
