2. Alyson Hannigan and Alexis Denisof
How I Met Your Mother star Alyson Hannigan, her fellow Buffy alum husband Alexis Denisof, and their two wee ones, Satyana and Keeva, dressed up as a family of sea horses. SEA HORSES. SPARKLY ONES. Goofy? A little. Wonderful? Definitely. Little Keeva, strapped to Dad’s chest, looks like she might have trouble seeing out from under her tiny seahorse headdress, but that’s okay. Because it is just too cute.
3. Liev Schreiber and Naomi Watts
Okay, so maybe this is only HALF of a family Halloween costume—Naomi Watt’s clown getup (not pictured) doesn’t quite go with the theme here—but Liev Schreiber’s spooky Grim Reaper costume and oldest son Sasha’s skeleton minion look are too good a pair to pass up. BOO!
Up next: To infinity and beyond!
