Martin Sheen will turn his back on acting in favour of education when he enrolls at Ireland's Galway University next autumn (07). The APOCALYPSE NOW star, who will study English literature, theology and philosophy, alongside oceanography, insists he has received no "proper education" since entering showbusiness. A spokesperson for the National University of Ireland (NUI) says, "We are developing that interest with him." Sheen was presented with an honorary degree by the NUI in the Irish capital Dublin last week (ends09APR06). He said at the ceremony, "I'm very serious about it."
