NEW YORK (AP) -- From "Star Trek: Voyager" to "Equus." Kate Mulgrew is joining "Harry Potter" star Daniel Radcliffe and Richard Griffiths in the revival of Peter Shaffer's "Equus," which opens Sept. 25 on Broadway.

Mulgrew will play a sympathetic magistrate who champions the case of a young man (Radcliffe) who blinds six horses.

Griffiths, who appeared with Radcliffe in a recent London production of the play, will portray a psychiatrist investigating the incident.

Preview performances begin Sept. 5 at the Broadhurst Theatre.

In addition to her "Star Trek" TV series, Mulgrew has appeared on stage as Katharine Hepburn in the one-woman play "Tea at Five."

Other casting will be announced at a later date.
