'Live with Kelly and Ryan' Halloween costume contest turns out impressive creations like a towering Bumblebee and a zipline

NEW YORK CITY -- Every year the audience of Live with Kelly and Ryan brings their A-game to the show's Halloween costume contest.

This year's entries were no exception.

Contestants often spend weeks or even months on their costumes. The pop culture references were current (like the shredded Banksy artwork), throwback (like Rosey the robot from the Jetsons) and everywhere in between.

Some weren't references at all: One man said his funky disco-themed costume came to him in a dream.

Sandy Kenyon reports on the 2018 'Live with Kelly and Ryan' Halloween costume contest.

Check out some of the most impressive and inventive costumes in the gallery below and videos above.
