Johnny Knoxville is no stranger to head injuries.

Hollywood’s Super Bowl weekend largely fizzled with the muted debut of Kenneth Branagh’s long-delayed Agatha Christie whodunit, “Death on the Nile,” a tepid reception for the Jennifer Lopez romantic-comedy “Marry Me” and modest box-office bumps for Oscar nominees.

It’s time again to celebrate Hollywood’s grandest ambitions and most daring risk takers.

“Jackass Forever,” the fourth movie in the anarchic stunt and prank series, earned $23.5 million in ticket sales in its first weekend in theaters, according to studio estimates Sunday.
