Cryptic Family Reunion: Any Title I Can Think Of Would Give Away The Theme To Somebody

Question

The answer to this puzzle is a list of ten thematically related words or proper names or phrases. Each of these is clued cryptically, and the theme is to be determined. Since the definition part of a cryptic clue would give away the theme, these cryptic clues use a family member (e.g., mom, sister) to stand in for the definition part of the clue. So for example, if the theme of the puzzle were chemical elements, "Sister picking at nit" would clue "tin". NOTE: Unlike many previous puzzles in this genre, clues are NOT sorted alphabetically; however, lengths of each answer are given with the clues. I hope you enjoy!
