Currently on Sky Premiere at the moment, this comedy with Ryan Reynolds and Jason Bateman wasn't an obvious choice of film to watch but I thoroughly enjoyed all of it and cried with laughter most of the way through.

Mitch (Ryan Reynolds) and Dave (Jason Bateman) have known one another since young boys and have been inseparable through most of life, but more recently they have begun to drift apart. Leading totally separate lives it is unclear at the start of the film, why they are best friends. Dave is a corporate lawyer who is very much at the mercy of his picky boss, a husband and a father of 3. Mitch on the other hand is single, an out of work actor and pretty much a bit of a loser! They both envy each other's lives, Mitch envy's Dave's money and his beautiful wife, while Dave envy's Mitch because of his lack of responsibilities and stress, and the amount of sleep he gets! Following a night out together they tell each other (while peeing in a fountain as you do!), that they wish they were each other and when they wake up the next morning, you guessed it - they are!

The film from the very beginning is very very funny. Mitch has a way with words which see him unable to communicate effectively as an adult and he isn't very aware of how he should behave in social situations - and he swears a lot! So when he switches with Dave, who is normally very serious and straight faced, and you see Dave sounding like Dave but behaving anything like Dave it is quite funny! While they try and figure out how to switch back, they must carry on living in the lives of each other. Mitch (in Dave's body) has to take over as a dad and a corporate lawyer in the middle of a very important merger at work while Dave (in Mitches body!) gets close to Dave's sexy associate Sabrina. Despite being given the freedom (as they wished) from their normal daily routines, they soon discover and find a new kind of respect for one another as they realise each other's lives in their own separate ways are very challenging.

Surprisingly there are special effects in this film and not like special effects I have ever seen before in my life! The first one happens pretty much in the opening scenes and involves Dave and changing time with one of his twin babies. I won't spoil anything but I seriously was not expecting what happened! Also, there is quite a bit of female nudity (come on girls, we get Ryan Reynolds so we have to give the men something!) but I'm going to burst the men's bubble here as I've just read a lot of it has been altered by CGI, in particular the women's breasts - there is a lord after all!

The film is fairly predictable, you see the end coming a mile off, and lots of the content in between, however how it gets there is thoroughly entertaining. Bateman and Reynolds make the perfect team in this and for me Bateman playing Mitch (in Dave's body) was just hilarious. His straight faced character mixed with Mitches offensive vocabulary work together to provide everything you would not want as the father of 3 children. Telling his daughter that violence IS the answer, and refusing to sing the 'Dinner time' song which without fail gets sung every dinner time, are just hilarious.

I have recommended this film to two sets of people, my dad and step mum who found it eye-wateringly hilarious, and my mum and step-dad who just didn't get it one bit, so I would say give it a try and see what you think - and let me know! I'd love to know what other people thought of it.
