Director Greta Gerwig 's film phenomenon remained a runaway No. 1 at the box office in its fourth week, bringing in $33.7 million, according to studio estimates Sunday.
The top pair had thin competition. The week's only major wide release, Universal's"The Last Voyage of the Demeter," finished fifth with a $6.5 million opening weekend. The sustained performance of the Mattel movie continues to flip the script on what had been a weak year in theaters, with major sequels underperforming including"Indiana Jones and the Dial of Destiny" and"Mission: Impossible -- Dead Reckoning Part I," which remained in the top 10 this week with $4.7 million.
