i go into this film expect a slasher and and while mute witness do take influence from say style of film making and this be much more than just your average slash flick . there be a number of thriller that focus on a certain disability blindness be more common ( blind terror and wait until dark and cat onine tail to name a handful ) and but the implication of have a mute lead in a thriller such a this be well portray and and actually integral to the plot a the fact that the lead character can not speak be often the reason why she find herself in dangerous situation that would be easy for anyone else to get out of . our mute witness be billy hughes and a make up artist work on a horror film production at a studio in moscow . she find herself lock in after hour one night and and after attempt to phone her sister for help and she stumble upon what at first appear to be the making of an illicit sex flick and but soon turn out to be a snuff movie . she try to convince the authority of what she see and but find that no one believe her story . recently hostel make the headline for show snuff movie making in a foreign country and but this film do it first and actually do a good job . it maybe not quite as nasty a eli roth opus and but the gore be more effective and and since director anthony waller ( who go on to direct one of my favourite modern thriller with the guilty ) implement a good sense of humour into the proceeding and mute witness be both sufficiently gory and fun to watch . the director certainly have a talent for craft suspenseful thrill ride and a this one never stand still . the plot be put into action quickly and and waller constantly introduces plot twist which give a big help hand to the overall entertainment value of the film . the act isn not bad for a b movie and with young performer marina zudina and fay ripley and evan richards deliver good performance . the atmosphere be gritty and and the russian location be suitably unfriendly and which help the film to retain a foreboding atmosphere . overall and mute witness be a much good film than you might expect it to be . the plot flow well and and the atmosphere and tension be spot on .
