The teen pop phenomenon Miley Cyrus scored another number one film at the box office this weekend with "Hannah Montana: The Movie", which opened to $34 million, according to studio estimates from Nielsen EDI.

The debut further illustrates the tale of the 16-year old star Hannah Montana who spends her days incognito as a regular school girl. This is Cyrus’ third number one score in less than two years, following her stellar numbers for the animated "Bolt" and the chart-breaking "Hannah Montana/Miley Cyrus: Best of Both Worlds Concert", all for Disney.

The auto epic "Fast & Furious" fell to second place with $28.8 million. The film, which reunites original stars Vin Diesel and Paul Walker, has earned $118 million in 10 days. "Monsters vs. Aliens" continues to find an audience, taking in $22.6 million this weekend for third place. The animated comedy is up to $141 million after three weeks.

Seth Rogen's R-rated comedy "Observe and Report" debuted with $11.1 million, while the Nicolas Cage thriller "Knowing" rounded out the top 5 with $6.7 million. After a month in theaters, it has grossed $68 million.

Box office grosses continued to tower over last year, jumping 62 percent over the same weekend in 2008. Final figures are due Monday.
