The Santa Clause (1994) -- Directed with Bill Elvin.
Good enough for kids with a premise that only sorta makes sense and seems often
unbelievable (and rule-less, in spite of the title) even for a fantasy movie.
Suggested viewing situation: on network TV in a loud, crowded room around
Christmas, not really watching it. (Michael Lembeck directed the sequel,
The Santa Clause 2.)
