I'm playing a game of Martian House Guest with myself again. That is, if a friendly creature from another planet were to plop its fluffy (I prefer fluffy . . . listen, it's my game) self into my brain for the first three weeks of April, what generalizations would the visitor draw from the theater I'll be watching, processing and reviewing on Broadway?

In case you have been elsewhere in the cosmos during previous mad dashes to the April cutoff for official Broadway seasons, this is what I mean.

Broadway producers, fearful that Tony nominators are incapable of remembering any show or performance that happened any time since the last season officially began April 25 of last year, stack piles of the biggest stuff right before the finish line. This year, that line is curtain time of April 23. Fifteen plays and musicals are pulling themselves together to open -- that is, if we count the two full plays of "Wolf Hall: Parts 1 & 2" separately. And except for "Skylight," the revival of David Hare's 1995 drama that opens April 2, all will be squashed between April 7 and 23.

But let's go back to the outer-space guest in my head. Aside from wondering what kind of crazy people cram so much hope, talent and money into such a tiny space-time continuum, a keen observer may well other surprising questions.

Do Earthlings worship the '50s movie musicals of director Vincent Minnelli -- particularly those starring Leslie Caron? In fact, for reasons unknown, Broadway will open a radically revised version of Minnelli's 1958 "Gigi" on April 8. Then, four nights later, we get a new adaptation of the late director's 1951 Caron vehicle, "An American in Paris." Coincidence? You decide.

Below please find our spring-madness catalog -- seven new musicals, five new plays, two musical revivals and a single play revival. My friend the Martian was confused when "The Heart of Robin Hood" abruptly backed out of the lineup, but encouraged that "The Visit," the long-wandering musical by John Kander and the late Fred Ebb, will finally land on Broadway as a late entry.

SKYLIGHT (opens April 2, Golden Theatre, 252 W. 45th St.) David Hare's intense encounter between former lovers, which starred Michael Gambon and Lia Williams on Broadway in 1996, brings Carey Mulligan and Bill Nighy from a sold-out run in London directed by Stephen Daldry ("The Audience") .

HAND TO GOD (opens April 7, Booth Theatre, 222 W. 45th St.) A young member of the Christian Puppet Ministry finds that his hand puppet is really the devil in this surreal and irreverent spoof by Robert Askins, transferring from an Off-Broadway hit.

GIGI (opens April 8, Simon Theatre, 250 W. 52nd St.) The musical best known for its movie flopped briefly in 1973. But Heidi Thomas has re-adapted Alan Jay Lerner's book to speak more to 21st century sensibilities while keeping his lyrics and Frederick Loewe's music intact. Vanessa Hudgens ("High School Musical") stars as the turn-of-last-century Parisian who is groomed to be a courtesan.

WOLF HALL: PARTS 1 & 2(opens April 9, Winter Garden Theatre, 1634 Broadway) This two-part historical epic, a transfer from a smash London engagement, is adapted from Hilary Mantel's award-winning novels about Henry VIII and his court.

Barrie found the lost boys.
