Los Angeles, June 3 (IANS) Hollywood heavyweight Mel Gibson who comes back to the big screen after a seven years hiatus, with thriller ‘Edge of Darkness’, seems to have taken a liking for unhappy roles.

While the Martin Campbell directed movie stars him as Thomas Craven, a homicide detective investigating the death of his activist daughter, his other two projects ‘The Beaver’ and ‘How I Spent My Summer Vacation’ also revolve around the sad lines.

‘Since I’ve passed the big 50, I’ve chosen my projects more carefully. When you realise that half of your life has gone by you don’t want to do stupid stuff anymore,’ Gibson said in a statement.

‘What does not kill you makes you stronger. Life’s experiences, whether they be pleasant, unpleasant, tortuous or excruciatingly wonderful and blissful, it seasons you somehow and you learn from it. Hopefully you learn,’ he added.

The 54-year-old also said he enjoys taking on unhappy roles despite how difficult they can be because it makes him appreciate his own life and so he simply likes to deal with them over and over again.

‘The Beaver’ is an idiosyncratic comic drama in which he plays a depressed father coping with his failures by communicating through a beaver hand puppet. While action drama ‘How I Spent My Summer Vacation’ shows him as a criminal stuck in a Mexican prison.

Having released in the US Jan 29 this year, ‘Edge of Darkness’ is being released in India June 25 by PVR Pictures.
