LOS ANGELES, May 4 (Reuters) - Marvel movie

"Thunderbolts" opened Hollywood's summer movie season with an

estimated $76 million in U.S. and Canadian ticket sales over its

first three days, distributor Walt Disney ( DIS ) said on

Sunday.

The returns were in line with pre-weekend forecasts, though

below the $88.8 million opening of Marvel's "Captain America:

Brave New World" in February.

"Thunderbolts" added $86.1 million in international

markets for a global total of $162.1 million, Disney ( DIS ) said in a

statement.

"Thunderbolts" stars Florence Pugh, Sebastian Stan and David

Harbour as anti-heroes who are forced to work together to fight

a supervillain. It is the 36th film in the Marvel Cinematic

Universe.

The movie business is still hovering below pre-pandemic

levels, and a healthy summer is key to that effort. Hollywood

brings in about 40% of the year's box office receipts during the

summer season, which the industry measures from the first

weekend in May through Labor Day, the first Monday in September.
