The above clip is from the movie "The Luck of the Irish" that premiered on Disney Channel. Pay attention to the dark haired man that barges in on the bus as well as the grandpa. Both are speaking with an irish accent. Now these two men don't necessarily seem like the typical irish characters that would be cast (they're missing the red hair, light skin and freckles) but hair and makeup has made them look the part. Looking the part is only half the battle, though, when auditioning.
Gareth Jameson, an actor and voice coach, has made several YouTube videos to teach you certain accents. Check out this video where he teaches the basics of an Irish accent:
