IMDB is often used as definitive guide.

But their numbering of Gilligan's Island is off.

For some dumb reason, they count the unshown pilot Marooned (with different cast members!) as episode 4.

And it throws all the numbering after off by one.

Don't be fooled.

Epguides and itunes shows it correctly.

And yet they have the "episode ratings" page correct.

gilligansisle.com frustrates me because such an obviously dedicated site has "Up at Bat" as a second season episode.

to me an un-aired pilot should be listed as #0, unless they are listing actual production numbers
