Warner Bros.-MGM’s “Hot Pursuit” has launched with a moderate $450,000 in Thursday night preview screenings in the U.S.

The buddy comedy, starring Reese Witherspoon and Sofia Vergara, has been forecast to open with a Mother’s Day weekend total of about $18 million at 3,003 locations — giving it a distant second-place finish to the second weekend of Disney-Marvel’s “Avengers: Age of Ultron.”

Critical response to the film has been overwhelmingly negative, and it has a 5% rating on Rotten Tomatoes.

“Hot Pursuit” is serving as a counterprogrammer to “Age of Ultron,” which is expected to dominate with a second weekend at around $85 million following its $191.3 million debut.  The first “Avengers” movie grossed an impressive $103 million in its sophomore weekend after debuting to a record $207.4 million in 2012.

“Avengers: Age of Ultron” has pulled in another $35.7 million during the Monday-Wednesday period to lift its U.S. total to $227 million in its first six days.
