Alicia Silverstone struggled to be taken seriously after starring in 'Clueless'.

The actress shot to worldwide fame playing ditzy blonde Cher Horowitz in the 1995 chick flick, and although she is grateful for the role she admits it was difficult to convince people she was not the same as her airhead character afterwards.

Speaking in an interview with Bullett Magazine, she said: 'I remember doing interviews in London for some movie at the time, and the interviewers would want to talk about the movie, of course, but all I wanted to talk about was murder.

'They probably expected me to be like the 'Clueless' character, but instead I was sitting there saying stuff like, 'And then they anally electrocute!' I pretty much bummed everyone out.'

'Clueless' director Amy Heckerling joined Alicia, 35, for the interview, and revealed she cast the actress for the part because she had a Marilyn Monroe-type quality needed for the film.

Amy said: 'When I was writing the script for 'Clueless', I had a vague notion in my head of Cher as a pretty, sweet blonde, who, in spite of being the American ideal, people still really like.

'You had that Marilyn Monroe thing, which is that other women love you, too.'

The pair reunited for upcoming motion picture 'Vamps', which sees Alicia playing a vampire in modern day New York City.

The film is released in October.
