Jack Black has proven himself to be one of the most prolific and acclaimed comedic actors working today, playing a part in a wide swath of exceptional comedies that make use of his talents both as a comic and as a talented musician, as a part of his band, Tenacious D. From cult classic comedies like 'School of Rock' and 'Nacho Libre' to exceptional animated blockbusters like 'Kung Fu Panda' and 'The Super Mario Bros. Movie', he has been a figure of cinematic greatness over the years.
However, as with any acclaimed actor who has been a part of the industry for decades, Black has also had his fair share of critical misfires that failed to land with audiences or critics alike. Whether it be long-forgotten fragments of his early acting career before he truly found his footing and hit his stride or more modern attempts that fail to recapture and capitalise on the actor's inherent strengths.
(If you like these films, that's fine, it's just a list. I will do a best of JB films soon)
