The star of “The West Wing” Martin Sheen is in Toronto this week to promote his new movie that he made with his son – Emilio Estevez’s- “The Way” and he’s making the most of his trip back to the land of his ancestors.

Sheen, 70, has been seen out and about enjoying the sites of Toronto and looks great doing so according to onlookers.

Sheen was having such a good time he even dropped his pants to show his underwear.

During a fundraiser for Haiti at the weekend Sheen offered to show his underwear to anyone who’d pledge $1,000 to the cause.

The money wasn’t long being raised and Sheen dropped his pants to the ground revealing briefs he received from Ellen DeGeneres, with her name still on the waistband.

Apart from raising money for charity, Sheen also used his time in Canada to speak up social issues.

Last Friday morning Sheen joined a picket line at the Fairmont Royal York to support hotel workers who were fighting for better hours and fewer cutbacks.

“I’ve been a union member all my adult life,” he told the Star at the time.

“I’ve been involved in labor struggles all my adult life.”

“The Way” is about Tom (Sheen), an American doctor who goes to France following the death of his adult son (Estevez), killed in the Pyrenees during a storm.

There he walks The Camino de Santiago, also known as The Way of St. James.

Tom's purpose is initially to retrieve his son's body.

However, in a combination of grief and homage to his son, Tom decides to journey on this path of pilgrims.

While walking The Camino, Tom meets others from around the world (three in particular), all broken and looking for greater meaning in their lives.

Along The Way, Tom discovers the meaning of one of the last things his son said (in a flashback) to his father.

“All of us are hungry for some kind of transcendence these days,” Sheen told The Star in Canada.

“Just as part of our humanity. We long for something bigger than ourselves and sometimes we get distracted by power or money. Maybe we even take the wrong kind of journey into the worlds of drugs and alcohol.”

Speaking on his other –troubled- son, Charlie, Sheen said,  “Charlie saw the film and he loved it. You know, everybody’s working out their own journey to salvation and we have no right to judge them on the way.”
