Highlander 2: The Quickening is the only non-James Bond sequel of Sean Connery’s career – and turned into the biggest critical and commercial mess of his career. Connery played Bond in seven movies, though his final appearance was in the “unofficial” outing Never Say Never Again. After hitting something of a fallow period during the early 1980s, Connery made a major comeback with The Untouchables and went on to front major hits like The Hunt for Red October and The Rock. Perhaps having felt confined by the 007 series, Connery largely avoided sequels for much of his career.
