star rating represent saturday night friday night friday morning sunday night monday morning dennis ( simon pegg ) suffer nerve on the last minute before his marriage to libby ( thandie newton ) and do a runner . year later and he stick in an unsatisfying job while she and their son be shack up with successful business tycoon whit ( hank azaria ) a charismatic american with lot to offer . but old and wiser and dennis vow to get his life back on track and win libby back to him by do the unthinkable . run the london marathon . i have mean to go and see rendition but i fancy a laugh so i go and give rfr a go instead . unfortunately i pay for laugh but get rather little of them and as well a a slow and slumberous story that take far too long to get go . i be also rather surprise at how liberal our censor appear to have become . the film be rat 12a and mean moreorless anyone of any age can see it and but the amount of time the f word be use and along with a lot of the sexually explicit joke and really make me wonder . performance wise and pegg just ain not up to his hot fuzz standard and newton manages to be little more than attractive eye candy and david walliams make his standard cameo appearance in a baker shop . there quite a lively soundtrack go on and it an amiable enough ride to the end . plus anything i say isn not really go to make much difference because the film be show for well over a month now and by the look of it be still really continue to rake it in . the british really like to flock out to have a laugh at one of their homegrown comedy and but seem to overlook all the flaw with them . .
