Screen star Eli Wallach, whose credits include classic westerns The Magnificent Seven and The Good, the Bad and the Ugly, has died at the age of 98.

The US actor, whose career stretched across 60-plus years, was described as the "quintessential chameleon" for the vast range of characters he has portrayed when he was given an honorary Oscar a little over three years ago.

New York-born Wallach's film career also included appearances The Godfather: Part III, How The West Was Won and Mystic River. Wallach also had an extensive TV career and continued to draw acclaim for his stage work. He continued to appear on screen into his 90s, including a role in the 2010 film The Ghost Writer, which starred Ewan McGregor.
