Paul McGann in "Helen" at the Globe Theatre in London
My advice to anyone who's in the UK during the run is GO! It's always interesting seeing these guys on stage; completely different medium. McGann has done theatre in the past but not often, so grab the opportunity if you can! The Globe is also a very cool place to see a play. Have a drink at the Anchor, just a bit east of the theatre, and sit where Samuel Pepys sat, watching London burn during the Great Fire of 1666.
