When Jackie and Michael are walking to Ned Devine's house and it is raining, Michael is carrying a black umbrella when the two are on the road. However, when they reach Ned's house, Michael has a different umbrella, which is tan with a brown stripe.
When the lotto man comes to the village the fist time to verify the ticket, Jackie states that he has left the little bag with the ticket in it in the phone booth. However, earlier when Jackie and Michael are making the call to the lotto we see Jackie placing a red bag with the ticket in it on top of the phone, but when they leave the phone booth there is clearly no red bag left behind.
When Lizzy is calling the National Lottery from the phone booth, it is clearly visible that the entry in the yellow pages is in fact a cut-out piece of paper glued onto a different entry.
Obvious eye movement of the "deceased" Ned during the scene where Michael and Jackie are playing with Ned's facial expressions. More prevalent when they are trying to reinsert Ned's teeth, and from the side view where his eyelashes can clearly be seen to flicker a couple of times.
