McFadden left the series at the end of the first season and was replaced by Diana Muldaur as Doctor Katherine Pulaski at the beginning of the second. An official announcement stated McFadden had left the series to pursue other career options. McFadden herself got a call from her agent who told her the producers had decided to go in another direction with the character. Like the other cast members, McFadden was surprised. Thanks to a letter-writing campaign, support from Patrick Stewart, and a personal invitation from executive producer Rick Berman, McFadden was brought back to the TNG cast for the third and subsequent seasons, with her only three appearances for season two being stock footage.
