'Guardians of the Galaxy' soars to new heights at the box office

"Guardians of the Galaxy" is soaring past the competition at the box office, claiming its place as the highest-grossing domestic movie of 2014.

It stars Chris Pratt and Zoe Saldana as the leaders of a group of galactic warriors.

Labor Day weekend ticket sales placed it number one for the third time since it's debut with $16.3 million in U.S. and Canadian ticket sales.

That sent its total domestic sales to new heights with more than $270 million so far.

Second at the box office this weekend is "Teenage Mutant Ninja Turtles" which brought in $11.8 million, according to studio estimates.
