David Schweizer (adaptor/director) seems to be under the spell of Henrik Ibsen’s epic “Peer Gynt,” even after a 40-year association with the play. Having staged the play in the ’70s at the Williamstown Theatre Festival, and in the ’80s at the Polish National Theatre, and then again for L.A.’s Actors Gang in the ’90s, he’s taking another stab at Ibsen’s dramatic poem (originally five acts, 40 scenes, 50 characters and five-hour running time) at the Potiker Theatre (La Jolla Playhouse), where it will run through July 24. It’s a co-production with Kansas City Repertory Theatre
