James Nesbitt stars in Bloody Sunday

This pledge will be helped by the anticipated attendance of actress Cate Blanchett, who stars in German director Tom Tykwer's Heaven.

Mr Tykwer is one of four German director's competing for the coveted Golden Bear award, the highest ever for the festival.

His 1999 Run Lola Run movie was greeted with critical acclaim.

"It's a strong showing for German film," said Mr Kosslick. "And I think it was time for that."

Charlie Chaplin

Former festival director Swiss Moritz de Hadeln was criticised during his 22-year reign for failing to use the festival as a platform for German films

A highlight of the two week event, which runs until 17 February, is a new print of Charlie Chaplin's The Great Dictator to be shown at a screening attended by members of his family.

In total 23 films will be in the running for the Golden Bear, including Bloody Sunday, which has already been screened on ITV.

Giovanni Ribisi and Cate Blanchett star in Heaven

Indian director Mira Nair is heading up the festival jury, having won the Golden Lion at the Venice Film Festival for Monsoon Wedding.

She will be joined by an international panel of judges.

A trio of Dame Judi Dench's films, The Shipping News, Iris and Chocolat, will be playing during the programme, showcasing the actress' prolific film career of recent years.

The French film, Intimacy, directed by Patrice Chereau won the top Golden Bear award in 2001.
