Many celebrity interviews can go bad, for many reasons. Uninformed journalists or their bad intentions, unprepared celebrities and the like. The unofficial king of bizarre interviews is Tom Cruise, though not only actors but many starlets, musicians, etc. can be classified in this category.
From the awkward interviews available, it can be concluded that there is a very fine line between a regular interview and the moment when it goes wrong, whatever the reason.
Sometimes such interviews are just ridiculous, sometimes uncomfortable, and sometimes cause anger at celebrities.
Some become so bizarre, some turn into a good joke away from the usual interview, and some are literally interrupted when celebrities realise that there is absolutely no point in continuing to participate in it.
