The film poster for Attack the Block aims to appeal to its target audience of 15-25 year olds. It depicts a group of teenage boys dressed in urban streetwear standing ready to fight off meteors falling from the sky, signifying the science fiction genre. The tagline "INNER CITY VS OUTER SPACE" further conveys the hybrid comedy/sci-fi nature. Additional elements like a diverse cast of characters, London-based setting shown through city skyline imagery in the background, and promotional text connecting it to the popular film Shaun of the Dead help broaden the appeal to wider audiences.
