Actor William Shatner is promising to uncover the truth about the guests on his new US TV chat show, which airs for the first time on Tuesday.

An appearance by Star Trek actor George Takei has also been mooted.
Shatner was upset after not being invited to the I'm A Celebrity star's wedding to his partner in September.
Takei's mananger told Reuters that the actor would like to appear on the show in the future after Shatner issued an invitation.

The actor appeared in the 1960s TV version of Star Trek and a number of subsequent films.
His other recent ventures include a business in which he signs keepsakes for fans while being filmed.
