Jenna-Louise Coleman is so short that she has to stand on old phone books when filming scenes with actor Matt Smith in 'Doctor Who'.

The actress made a surprise appearance on the opening show for the new series on BBC1 which aired on Saturday (01.09.12).

During her scenes with the Time Lord it was discovered that Jenna needed a step up in order for the close-ups.

A source from the show said: "It's funny that Jenna will be travelling around the galaxy in a phone box and now has to use phone books to stand on to look taller."

Measuring in at 5ft 2in the 26 year-old ex-'Emmerdale' star - who is replacing Karen Gillan as the Doctor's assistant in the show - is almost a foot smaller than Matt Smith.

Her character Oswin Oswald will join the series full-time in this year's Christmas episode.

Guest stars in this weekend's Doctor Who include Harry Potter's Mark Williams (Arthur Weasley), 53, and David Bradley (Argus Filch), 70.
