the most fertile man in ireland revolves around eamon manley who be 24 year old and still happen to be a virgin . he live with his mother in belfast . he be also a very shy guy towards woman . everything have change for eamon when he be seduce by a woman ( as far a i can remember a neighbour ) . it be not because he loose his virginity but he discover that he have a super power . despite have protection and this neighbour become pregnant . he be tell by the doctor that he have very high sperm count . his mother brilliantly come up with an idea which make u see ginger head baby all around in the end of the film . he start help out woman in both side of belfast to conceive baby . first voluntarily then with the help of his colleague run a business out of it . the most fertile man in ireland have it funny moment but need to come up with good joke and with a good script . i couldn not help think that it give me the impression of a tv sitcom rather than a movie . kris marshall be a different name on the silver screen but do not shine a star . it more like the guy you saw in such and such movie . like him be in love actually ( i think he be very funny in that one ) . well and it be okay to watch but couldn not help doze off from time to time . out of .
