HERMAN will have a star acting role in a new MGM film he will shoot in Hollywood in September.     This will be Herman's first role as a film actor, although he has appeared in Granada's top-rating "Coronation Street" as Len Fairclough's son.     Herman leaves for the States this Sunday.     During this current trip, Herman will make guest appearances in MGM's "Girl Crazy."

Press demands have been so great that Freddie and The Dreamers will come in a day early and spend the entire day of April 19 doing interviews and photo sessions.     Almost the same impact has been scored by Herman's Hermits.     Last week M.G.M. finally got the O.K. to release "Mrs. Brown You've Got A Lovely Daughter," from their first album, "Introducing Herman's Hermits" which is currently in the top five and still climbing. On a 425,000 advance order, the single flew into the "Billboard" Top Twenty at Number 12.     Never has the demand for any single from an album, been so great, DJs all over the country pulled the track for airplay, and in several parts of the country the track was Number One on station playlists weeks before M.G.M. decided to release it as a single.     As in England, Herman is fondly referred to by America's young set as "The one with the tooth." They also dig the fact he's only 17 which, in this country is a tremendous point in his favour.     Herman, too, has secured a spot on the Ed Sullivan Show. He appears on June 6, and guests on "Hullabaloo" on May 4. They headline the Dick Clark package from April 30 through June 2, and play independent dates both before and after.
