Los Angeles ? Football season started early as Mark Wahlberg’s “Invincible,” a Walt Disney tale about a real-life walk-on who signed with the Philadelphia Eagles in the 1970s, debuted as the top weekend movie with $17 million.

The previous No. 1 flick, New Line Cinema’s “Snakes on a Plane,” lost altitude in its second weekend, falling to sixth place with $6.4 million, a steep 58 percent drop, according to studio estimates Sunday.

“Snakes on a Plane” had been preceded by a whirlwind of Internet buzz that the movie failed to live up to, opening with a modest $15.2 million. Starring Samuel L. Jackson as a federal agent battling killer snakes on a redeye flight, the movie had taken in $26.5 million in 10 days.

“Invincible” stars Wahlberg as Vince Papale, a substitute teacher who made the Eagles’ special-teams squad in open tryouts. The movie was the latest success among Disney’s inspirational sports tales, which include the baseball flick “The Rookie” and the hockey saga “Miracle.”

“They make people feel good, and they can relate to the underdog,” said Chris LeRoy, general sales manager at Disney. “They are sports-related stories, but I think these movies transcend the sport and get right to characters that people relate to.”

The Warner Bros. drinking comedy “Beerfest” opened in fourth place with $6.5 million. Universal Pictures’ musical drama “Idlewild,” starring Andre Benjamin and Antwan A. Patton of OutKast, premiered at No. 9 with $5.9 million.

“Idlewild” scored the best per-theater numbers among new wide releases, averaging $6,064 in 973 cinemas, about one-third the locations for “Invincible,” which averaged $5,838 in 2,917 theaters, and “Beerfest,” which did $2,193 in 2,964 sites.

New Line’s family comedy “How to Eat Fried Worms,” about a boy goaded into devouring worms, opened at No. 11 with $4.05 million, averaging $2,166 in 1,870 theaters.

Expanding to its widest release yet, Fox Searchlight’s independent hit “Little Miss Sunshine” climbed to No. 3 with $7.5 million, averaging $5,245 in 1,430 theaters. A black comedy starring Greg Kinnear, Toni Collette and Steve Carell in the tale of a family’s calamitous trip to a child’s beauty pageant, it had taken in $23 million since opening in a handful of theaters a month ago.
