Terminator: The Sarah Connor Chronicles starred Brit Lena Headey

Terminator: The Sarah Connor Chronicles - the big budget US TV series based on the film franchise - has been cancelled, broadcaster Fox has said.

The show, which starred British actress Lena Headey, ran for two seasons and was shown in the UK on Virgin1.

It was set after the events of the second instalment of the film series.

Meanwhile, US sitcom Samantha Who? starring Christina Applegate has also been axed after two seasons, according to trade paper Hollywood Reporter.

It said ABC had offered to renew the comedy - shown in the UK on E4 - if the producers cut $500,000 (£325,000) from the show's budget.

But both the network and producers had decided to pull the plug, the paper added.

Drama record

Fox, which on Monday was the first of the networks to reveal its autumn schedule, announced six new series including musical comedy Glee, about a high school choir.

NBC is expected to announce on Tuesday that it is renewing legal drama Law & Order for a 20th season, which means it will equal the record for US TV's longest-running primetime drama.

It will match Western drama Gunsmoke, shown on CBS, which ended in 1975.

Meanwhile, NBC has announced that comedian Will Ferrell and rock band Pearl Jam will appear on Conan O'Brien's first Tonight Show on 1 June.

The presenter takes over from Jay Leno, who has presented the show for 17 years.
