Former ITN newsreader, Sir Trevor McDonald, will be seen getting into a fracas with a Hollywood movie star tonight.
Sir Trevor can currently be seen presenting his new series The Mighty Mississippi, the second episode of which airs tonight at 9 on ITV.
In the series, he is following the course of the river from the Gulf of Mexico to its source and meeting the people who are directly affected by it. Last week, he examined the devastation caused by Hurricane Katrina on New Orleans, and visited the slave quarters of a cotton plantation.
But tonight things get out of hand when he meets with screen legend Morgan Freeman, famous for his roles in movies such as Shawshank Redemption and Driving Miss Daisy.
Mr Freeman becomes annoyed when despite several denials, Sir Trevor insists on pursuing why he agreed to do the voiceover work for the More Than insurance TV ads.
"And why on earth did you agree to call yourseld More Than Freeman?" he asks at one stage.
When Mr Freeman threatens the presenter with a broken whiskey bottle, Sir Trevor is heard to exclaim: "Typical noncey Hollywood star - likes to take the money but won't admit to doing the ads..." before the camera is switched off.
A spokesman for Mr Freeman said: "This is a complete stitch-up. He never done no ads for no insurance."
