Silent "thrill comic" Harold Lloyd takes on modernity in this 1923 classic about a go-getting youth who risks life and limb in his quest for success in the big city. The nail-biting climax where he climbs the side of a department store culminates in one of the most famous images in the whole of cinema. Digitally projected. Astor, tomorrow, 7pm. Double bill with Speedy.

THE PICTURE OF DORIAN GRAY (105 minutes) PG

Albert Lewin's 1945 production is the definitive screen version of Oscar Wilde's decadent fable about a young dandy (Hurd Hatfield) blessed or cursed with the secret of eternal youth. George Sanders rattles off epigrams by the dozen as the hero's amoral mentor, while the young Angela Lansbury will break your heart as a pert yet vulnerable music-hall star. Screens in conjunction with the Whistler's Mother exhibition. Digitally projected. NGV International, today, 2pm. Free, limited seats.

ON THE BEACH (129 minutes) PG

Stanley Kramer's 1959 vision of the end of the world in Melbourne has an abiding fascination for those familiar with the city – and maintains dramatic power through its sheer relentless gloom. Gregory Peck leads the "all-star" cast, but it's Ava Gardner who stands out against the grey post-apocalyptic backdrop as a life force. Digitally projected. Sun Theatre, tomorrow, 12.30pm.

MEAN GIRLS (97 minutes) M

Mark Waters' 2004 teen comedy is probably the last real classic of the genre, with Lindsay Lohan showing equal parts ditziness and pluck as an intrepid innocent who goes astray in the jungle of high school. The knowing script is by Tina Fey, who gives a sharp supporting performance as a well-meaning teacher. Digitally projected. Astor, today, 7.30pm. Double bill with Whiskey Tango Foxtrot.

FINDING DORY (103 minutes) G

The aquatic adventure Finding Nemo was deservedly one of the Pixar animation studio's biggest hits. This sequel recreates the formula, dispatching the absent-minded blue tang fish Dory (Ellen DeGeneres) on a quest of her own. As in the earlier film, the excellent voice actors supply nuance while the character designs borrow from actual marine life with a cartoonist's freedom. General.
