How did Santa Claus get to be, well...Santa Claus? And what if he wasn't the selfless and jolly magical figure we thought he was? That's the idea behind The Santa Clause, the 1994 comedy film starring Tim Allen. Directed with childlike wonder by John Pasquin with a genuinely humorous and touching screenplay by Leo Benvenuti and Steve Rudnick, the film revolves around businessman Scott Calvin (Allen) who causes the real Santa to slip and fall from his roof. What he doesn't realize is that by putting on the jolly man's red coat, he has committed to take over the role of Santa — and it's harder than it seems.

It's a simple concept, but one that the film does successfully, with memorable characters, a fully committed cast, and a grounded-yet-magical mythology. Audiences seemed to agree, with the film earning over $144 million against a $22 million budget in addition to yielding two sequels, The Santa Clause 2 in 2002 and The Santa Clause 3: The Escape Clause in 2006. Despite diminishing financial returns, both follow-ups maintain the sense of wonder and whimsical fun established by the first film while continuing the story of Scott and his Santa "clauses" in new and (mostly) innovative ways.

Whether you're sipping hot cocoa while marathoning the trilogy from your couch or just looking for a refresher on the familiar faces in the North Pole and beyond, here's a handy guide to who's who in the trilogy, from Santa to Jack Frost and everyone in between.

He has a strong belief in the spirit of the season and helps his dad understand Santa's importance. Charlie appears in The Santa Clause 2 as well as The Santa Clause 3, where he has grown from a sweet, innocent kid into a sullen and angry teenager who resents that his dad is never around.

Laura is Scott's ex-wife and Neal's wife. Along with Neal, she is alarmed when she believes that Scott is trying to persuade Charlie that his father is really Santa Claus. Despite Scott's claims against it, his changing weight, beard growth, and ravenous sweet tooth lead Laura to think that Scott has gone off the deep end of delusion. Laura's doubts are washed away, however, when Scott convinces her that he really is Santa, gifting her with the childhood game she'd always wanted: Mystery Date. Laura appears in both of the film's sequels, along with Neal and their daughter Lucy.

Neal is Laura's husband and Charlie's stepfather. He is a psychiatrist who tends to believe only in what he can see.

He's even more horrified when he believes that Scott is deliberately changing his appearance to play into the idea that he's Santa. After believing that Scott is suffering a mental break, Scott eventually manages to convince Neal that he really is Santa Claus, bolstering his belief by giving him the one gift Neal always wanted as a child but never received: an Oscar Mayer Weenie Whistle. Neal appears in both of the film's sequels.
