Duplicate Keywords - List #3 (Proposal for Permanent Merging and Auto-Conversion)

Here is the third installment in my list of duplicate keywords proposed for permanent merging and auto-conversion.

As with my prior lists, I propose that the IMDb community be allowed one week to review and comment on this list before I formally submit it to IMDb staff for action.

Every duplicate keyword (or combination of multiple keywords) on this list has at least 50 titles.

The mergers should be made in the direction of the arrows.

Many of these would merge the keywords to the American spellings, per IMDb policy. However, I do recommend keeping the British spelling for "british-humour," which is, after all, a British-specific keyword.
