The actor achieved prominence and critical acclaim in the early 1990s with films such as Patriot Games and Jurassic Park, before cementing his icon status in recent collaborations with Quentin Tarantino, including Django Unchained and The Hateful Eight.

And Samuel reveals he plans to hit the 200 movie milestone before he slows down.

Appearing on The Late Show with Stephen Colbert on Wednesday night (29Jun16), Samuel spoke about how he was honoured to receive the Lifetime Achievement Award at the BET Awards last Sunday (26Jun16), but made it clear the prize doesn't mark his retirement.

"It's kind of funny because it happens and you go, 'So am I supposed to slow down or stop working now?' So I'm not sure," he laughed. "Actually, somebody told me, 'Well, you're up to 165 (movies)', so I've got to do at least 35 more movies to get to 200."

The 67-year-old added that he makes four or five movies per year, and accordingly, spends more time overseas on film sets than he does in Hollywood.

"I'm out more than I'm at home," he laughed, as he explained he's currently jetting between Los Angeles, Amsterdam and Bulgaria due to commitments for filming The Hitman's Bodyguard with Ryan Reynolds.

The prolific actor, has now starred in over 100 films, and is the second highest grossing actor in U.S. box office history, behind Star Wars' Harrison Ford, with his movie hits banking $4.6 billion (£3.4 billion).

Samuel also discussed his part in new film The Legend of Tarzan, in which he plays historical figure George Washington Williams. While the character of Tarzan is of course fictional, he explained that Williams was the first African-American to travel to King Leopold II's Congo Free State, where he was shocked by the suffering of the region's people, and spurred the first public outcry against the regime in 1890.

"He wrote letters to various governments... telling them what he (Leopold) was doing, and to stop supporting them," he related.

The Legend of Tarzan opens on Friday (01Jul16) in the U.S. and on 6 July (16) in the U.K.
