According to the Daily Mail, “The X-Files” heroine Gillian Anderson will take the lead in Rebecca Gilman’s play The Sweetest Swing In Baseball at the Royal Court in March 2004. Calista Flockhart, who had been expected to do Eugene O’Neill’s Anna Christie, has said she’s not about to pack her bags and head for London. The former “Ally McBeal” star apparently wants to devote more time to her relationship with boyfriend Harrison Ford. The play was to have been produced by Sonia Friedman. It is not known whether it will still go ahead with someone else in the role.

Gillian Anderson came over last year for a workshop of Gilman’s play, which is about a painter who has to re-assess her life when her exhibition is trashed by the critics. Anderson’s last London stage outing — she co- starred with Roger Allam in the two-hander What The Night Is For (at the Comedy Theatre) — received a mixed reception.

According to the Mail, Royal Court boss Ian Rickson will direct, with Kate Harper and Nancy Crane co-starring. The show will open on Mar. 31.
