Treacle Jr. is a 2010 British film written and directed by Jamie Thraves and starring Aidan Gillen, Tom Fisher, and Riann Steele.

In the morning, he throws his phone into a lake, bins his bank cards (eventually retaining a family photo) but keeps his money.

That night, drinking in the park, he is attacked by a gang of youths; fleeing, he runs into a tree, injuring himself.

Aidan takes Tom to show him a drum kit he is saving for, having dreams of fame.

Depressed, Tom takes out the family photo, and finds a bank card, which he uses to withdraw cash.

The next day, Aidan takes Tom to the Horniman Museum and they enjoy making music with the instruments for public use.

Linda, allergic to cats, finds the kitten hidden in the wardrobe and attacks Aidan.

Tom then menaces her with a knife, grabbing her by the throat and demanding she confesses to stealing the money.

Peter Bradshaw of The Guardian gave the film three out of five stars, describing it as a "low-key portrait of a south-east London odd-job man with a big performance by Aidan Gillen, and the return of promising film-maker Jamie Thraves".
