TVLine Items: Olsen Twins on Nickelodeon, New Arrow Boss and More

So Little Time Nickelodeon

Have we collectively time-traveled back to the ’90s? Because the Olsen twins are suddenly everywhere.

On the heels of Netflix’s Full House revival becoming a reality, Nickelodeon announced Thursday that it has acquired Mary-Kate and Ashley Olsen’s library of series, TV movies and music video specials.

Among the titles acquired are The Adventures of Mary-Kate & Ashley, You’re Invited to Mary-Kate & Ashley’s, So Little Time, Mary-Kate and Ashley In Action!, Fashion Forward, Our Lips Are Sealed, Winning London, Holiday in the Sun, When in Rome, Getting There: Sweet 16 and Licensed to Drive and The Challenge. [Editor’s note: None of these are products of our imagination — we promise!]

So Little Time — the Olsen twins’ 2001 sitcom — will be the first title to air, debuting on Nickelodeon April 27 at 7:30 pm. Episodes will air every weekday, before the rest of the catalog is rolled out throughout the year.
