Mel is currently in Ireland working on pre-production for The Professor and the Madman, which the actor-director will both star in and produce.

The film, which also stars Sean Penn, is set in the mid-19th century and relates how the first Oxford English Dictionary was written by a professor largely assisted through his correspondences with a doctor in an insane asylum.

Mel has been spotted all over the city, at The Tiger Dublin Fringe Festival, FX Buckley and Matt the Thresher, to name just a few places.

The latest shows him enjoying the Irish scenery of Wicklow. He was spotted on the Sugar Loaf by singer Heather Fogarty and her friends Michael O'Connor and Shane Gallagher, and the Braveheart star gladly snapped pics with them.
