The Speaker of the House of Representatives is next in the line of Presidential succession. However, this would require that both offices, President and Vice President, be simultaneously vacant. This is much less likely following the enactment of the 25th Amendment, which provides for a replacement Vice President whenever the position is vacated.
According the current Presidential Succession Act (3 USC § 19), the order of succession if both the President and Vice President die, are removed from office, and/or are unable to perform the duties of President is:
Speaker of the House
President pro tempore of the Senate
Secretary of State
Secretary of the Treasury
Secretary of Defense
Attorney General
Secretary of the Interior
Secretary of Agriculture
Secretary of Commerce
Secretary of Labor
Secretary of Health and Human Services
Secretary of Housing and Urban Development
Secretary of Transportation
Secretary of Energy
Secretary of Education
Secretary of Veterans Affairs
Secretary of Homeland Security
(The cabinet members are ordered in the line of succession according to the date their offices were established.)
Note that a President is required to be born a citizen, to be at least 35 and to have lived in the US for 14 years. If the next in line does not meet these requirements, he or she will be passed over on the list.
Note also that line of succession applies only to the office of the Presidency. Once one of those in the succession becomes President; that person appoints a new Vice-President with the advice and consent of the Senate.
Before 1967
Prior to the ratification of the 25th Amendment in 1967, there was no provision for filling a vacancy in the vice presidency. When a president died in office, the vice president succeeded him, and the vice presidency then remained vacant.
If the president died or left office when there was no vice-president, the President Pro Tempore of the Senate would have become president, and next the Speaker of the House. The Speaker assumed the top position in 1947, after the period 1886-1947 when only Cabinet officers were in the line of succession.
If both the President and the Vice President are unable to serve, then the Speaker of the U.S. House of Representatives would become President.

If the President can not complete his term, the vice-president becomes President. If the vice-president can not complete his term, the president nominates a new vice-president who must be confirmed by both houses of Congress in order to take office. If two were both suddenly killed, the Speaker of the House would become President.
According to Amendment XXV to the U.S. Constitution (ratified February 10, 1967), if the President is removed from office, or if the President dies or resigns, the Vice President becomes President. Whenever there is a vacancy in the office of the Vice President, the President nominates a Vice President who takes office upon confirmation by a majority vote of both Houses of Congress.
Amendment 25 gives a process for filling a vacancy in the office of vice president.What happens is that the new President names someone to fill the position and if both houses of Congress approve, he becomes vice president.
The Vice President, who has now become the President, chooses someone to fill the position of Vice President. That nominee then must be ratified (approved) by both Houses of the U.S. Congress. According to Amendment XXV to the U.S. Constitution (ratified February 10, 1967), if the President is removed from office, or if the President dies or resigns, the Vice President becomes President. The amendment also provides for the situation where the President is temporarily disabled, such as if the President has a surgical procedure or becomes mentally unstable. Whenever there is a vacancy in the office of the Vice President, the President nominates a Vice President who takes office upon confirmation by a majority vote of both Houses of Congress.
They are both part of the Office of Managment and Budget.
The President has to nominate someone to be Vice President, but that said person can only be Vice President with the majority vote of both Houses of Congress
If the President can not complete his term, the vice-president becomes President. If the vice-president can not complete his term, the president nominates a new vice-president who must be confirmed by both houses of Congress in order to take office. If two were both suddenly killed, the Speaker of the House would become President.
It is not quite true because when the office of Vice-President becomes vacant, the President chooses a new Vice-President who then must be approved by both houses of Congress before he can take office. ( 25th amendment.)
If both the president and vice president die, the Speaker of the House of Representatives becomes the President of the United States.

According to Amendment XXV to the U.S. Constitution (ratified February 10, 1967), if the President is removed from office, or if the President dies or resigns, the Vice President becomes President.
