Robert the Bruce, although not a sequel, picks up where the events of Braveheart left off and stars Angus Mcfaden (who also co-scripted) and Jared Harris. The Blu-ray release comes with a commentary and a featurette.
Titus is most certainly an ambitious film and while I didn’t particularly enjoy it and doubtful I’ll ever revisit it, it’s not a complete waste of time, well worth seeing for Anthony Hopkins and Jessica Lange.
