Undersea War

The film, Aquaman (see also here and here), has up-to-date cinematic special effects, including underwater battle scenes. We want to see cinema adaptations of:

the encounter with the aquatic being in "The Horn of Time the Hunter" (see here);

the fight against the aquatic monster, A'u, in "The Game of Glory" (see here);

the fight against the kraken in The Merman's Children (see here);

the exorcism of Liri and the long swim across the Atlantic in The Merman's Children (see here).

The sea, like the atmosphere and interplanetary space, is a three-dimensional environment so we can vicariously enjoy the adventures of beings free to move in three directions.
